SUMMARY:Cosmic Microwave Background Science from the South Pole Telescope and Beyond by Dr. Srinivasan Raghunathan
DESCRIPTION:Abstract: Observations of cosmic microwave background (CMB) have played a critical role in establishing the standard cosmological paradigm\, the six-parameter Lambda Cold Dark Matter (LCDM) model. Besides the primary CMB anisotropies\, which contain a wealth of information about the primordial universe\, the secondary anisotropies of the CMB are also remarkable probes of the origin\, growth\, and evolution of structures in the Universe. These secondary anisotropies arise due to the interaction of CMB photons with the matter in the universe with the prominent ones being gravitational lensing and Sunyaev-Zeldovich (SZ) effects besides other fainter signals. In this talk\, I will present the South Pole Telescope (SPT)\, a 10-metre diameter telescope located at the geographic South Pole\, and the current efforts for mapping the CMB using SPT-3G\, the third generation camera on SPT. Next\, I will show some of the recent and upcoming results from SPT-3G which include cosmological inference from both the primary and secondary anisotropies. I will also present a detailed case for using the secondary anisotropies to shed light into some of the long-standing quests in the field of cosmological physics namely the physics of the epoch of reionisation\, properties of dark energy and neutrinos\, and the effect of baryonic feedback on structure formation using SPT and the upcoming CMB surveys like Simons Observatory and CMB-S4 experiments.

DESCRIPTION:About the speaker: Prof Olivier DORÉ is Principal Scientist\, Group Supervisor (2015-2019)\, Jet Propulsion Laboratory (JPL)\, NASA/Caltech and also Senior Faculty Associate in Theoretical Astrophysics\, at Division of Physics\, Mathematics and Astronomy (PMA)\, Caltech. He did his PhD from Institut d’Astrophysique de Paris (IAP) In 2001. After that he was Postdoctoral Research Associate in Princeton University (2002-’05) and Canadian Inst. of Theoretical Astrophysics (CITA) (2005-’09). Prof. Dore has been awarded several prestigious awards such as JPL Mariner award\, Gruber 2012 Cosmology Prize\, Gruber 2018 Cosmology Prize\, Breakthrough Prize in Fundamental Physics 2018\, JPL Explorer award and many more. He is Project Scientist in SPHEREx mission and Nancy Grace Roman Space Telescope for which he is leading the team focused on cosmology with large scale structures. Other than these two experiments he has been several other missions such as SPIDER\, Planck HFI (Core Team)\, WMAP (2003-2006)\, Euclid\, and the LSST Dark Energy Science Consortium (DESC). \nAbstract: SPHEREx\, a NASA Medium Explorer (MIDEX) mission scheduled to launch in early 2025\, is designed to spectrally survey the entire sky using a small cryogenic wide-field telescope combined with novel (but simple) spectrometers.  SPHEREx will probe the inflationary birth of the universe by studying large-scale structure\, complementing surveys optimized to constrain dark energy. SPHEREx will investigate the origin of water and biogenic molecules\, locked in interstellar ices in the early phases of planetary system formation. SPHEREx will also chart the origin and history of galaxy formation through a unique mapping method in two deep survey fields. Following in the tradition of all-sky missions such as IRAS\, COBE and WISE\, SPHEREx will be the first all-sky near-infrared spectral survey.  During its two-year mission\, SPHEREx will produce four complete all-sky maps with over a billion detected galaxies\, hundreds of millions of high-quality stellar and galactic spectra\, and over a million ice absorption spectra\, enabling diverse scientific investigations. In this presentation\, I will give a mission status and focus on the inflationary science.

SUMMARY:Do We Understand Cosmic Structure Growth? by Prof. Blake D. Sherwin
DESCRIPTION:About the speaker: Prof. Blake D. Sherwin is a Professor of Cosmology and Astrophysics at the Department of Applied Mathematics and Theoretical Physics (DAMTP)\, University of Cambridge. He obtained his PhD from Princeton University in 2013. After that\, he was a postdoctoral fellow at UC Berkeley\, Lawrence Berkeley Laboratory\, and the University of Cambridge. Then\, he became an assistant Professor at Cambridge in 2017. He has been awarded several honorable awards and fellowships\, such as the Miller Research Fellowship\, NASA Einstein Fellowship\, and STFC Ernest Rutherford Fellowship. He is part of several international CMB experiments such as Atacama Cosmology Telescope (ACT)\, Simons Observatory (SO)\, LiteBIRD and CMB-S4. \nAbstract: One of the most powerful tests of our cosmological model is to verify the predicted growth of large-scale structure with time. Intriguingly\, many recent measurements have reported small discrepancies in such tests of structure growth (“the S8 tension”)\, which could hint at systematic errors or even new physics. Motivated by this puzzling situation\, I will present new determinations of cosmic structure growth using CMB gravitational lensing measurements from the Atacama Cosmology Telescope (ACT). These ACT DR6 CMB lensing measurements allow us to directly map the dark matter distribution in projection out to high redshifts; new cross-correlations of CMB lensing with unWISE galaxies also allow us to probe the matter tomographically. I will discuss the implications of our lensing results for the validity of our standard cosmological model as well as for key cosmological parameters such as the neutrino mass and Hubble constant. \nThe recording of the talk is available on the CMB-Bharat YouTube channel.

SUMMARY:Parity Violation in Cosmology by Prof. Eiichiro Komatsu
DESCRIPTION:About the Speaker: Prof. Eiichiro Komatsu is the Director of the Department of Physical Cosmology\, Max Planck Institute for Astrophysics in Garching\, Germany. He obtained his doctoral degree from Tohoku University in Japan in 2001. While working on his doctoral thesis\, he joined the WMAP science team at Princeton\, where he later did his postdoc. Komatsu joined the University of Texas at Austin in 2003 as a faculty member and then became the Director of the Texas Cosmology Center. In 2004\, he received the Young Astronomers Award from the Astronomical Society of Japan for his work on constraining inflationary models of the early universe\, and in 2010\, the Nishinomiya-Yukawa Memorial Prize for physics for his studies of the early universe\, as well as several other awards and fellowships. He is interested in and works on all aspects of physical cosmology. \nAbstract: Parity symmetry is known to be violated in the weak interaction. Do the physical laws behind the unsolved problems of modern cosmology – cosmic inflation\, dark matter\, and dark energy – also violate parity symmetry? In this talk\, we will discuss theoretical and observational possibilities of parity violation in cosmology\, a topic that has received much attention in recent years. \nThe recording of the talk is available on the CMB-Bharat YouTube channel.

SUMMARY:Machine Learning in Cosmology - Whither the CMB? by Prof. Benjamin D. Wandelt
DESCRIPTION:About the Speaker: Prof. Wandelt (Ph.D. in astrophysics from Imperial College\, London) held early career research fellowships at the Theoretical Astrophysics Centre (Niels Bohr Institute) in Copenhagen and at the Department of Physics at Princeton University. In 2001\, he became assistant professor in the Departments of Physics and Astronomy at the University of Illinois at Urbana-Champaign\, receiving tenure in 2006. In 2010 he was awarded the International Chair of Theoretical Cosmology at Sorbonne University and the Institut d’Astrophysique de Paris. In 2011 he was the founding co-director of the Institut Lagrange de Paris in cosmology\, astro-particle\, and theoretical physics and was named director in 2014. Professor Wandelt has held long-term visiting faculty positions at the Max Planck Institute for Astrophysics; Caltech; Princeton University; the Institute for Advanced Studies\, Princeton; and NYU; and joined the Center for Computational Astrophysics at the Flatiron Institute in New York City in 2017. \nAbstract: In our endeavor to unravel the universe’s origins\, composition\, evolution\, and destiny\, we turn to the cosmos’ vast data reservoir: the cosmic microwave background (CMB)\, galaxy surveys\, supernovae\, and space-time distortions from astrophysical events. This talk delves into novel methodologies for merging cosmological theory with these diverse data sets\, with a special focus on potential for current and future CMB experiments. The advent of Artificial Intelligence and Machine Learning is revolutionizing our approach\, enabling sophisticated\, end-to-end Bayesian reasoning for previously intractable problems and opening new avenues for extracting insights from current and future CMB data. I will explore how these technological advancements are not only reshaping our analytical capabilities but also inspiring fresh cosmological perspectives. The discussion will cover the current state\, emerging opportunities\, and challenges in this field\, aiming towards the ambitious goals of reconstructing the universe’s initial conditions\, comprehending cosmic structure formation\, and probing dark matter and dark energy in a way that could redefine our understanding of the cosmos. \nThe recording of the talk is available on the CMB-Bharat YouTube channel. \n\n\n\n \n\n
