SUMMARY:Psychology Seminar Series: Critical and Sociocultural Perspectives in Psychology
DESCRIPTION:Abstract: Traumatized\, Narcissistic\, Co-dependent" — Our everyday narratives are influxed with Psy-language. They compel us to understand our experience and that of others in certain predictable ways — a looping effect of sorts. Sometimes this can be immensely helpful as we find support and community; at other times\, they can disconnect\, alienate\, and inform our identity in negative ways. In this talk\, we will interrogate these categories by looking at the diagnostic frameworks that inform them and consider the scandals that have historically plagued them\, in turn bringing forth questions about their validity\, applicability\, and claims of acontextuality.  \nAbout the Speaker: Ayurdhi Dhar is the founder and chief editor of Mad in South Asia. She is an assistant professor of psychology at Amity University\, Mohali and visiting faculty at Prescott College\, Arizona. Dhar is the author of Madness and Subjectivity: A Cross-Cultural Examination of Madness (Routledge)\, and has previously served as the newsletter editor of American Psychological Association’s Division 24. She has worked as a spotlight interviewer and reporter with Mad in America for 8 years and interviewed eminent figures in academia and beyond to spread awareness about the harms of a-cultural and a-contextual psychological knowledge\, indigenous resources in the global south\, and decolonization of the psy-disciplines.

SUMMARY:Mathematics Colloquium
DESCRIPTION:Dear All\, \nThe Department of Mathematics invites you to the Colloquium ​on November 06\, 2025 \nTitle: Amenable actions for groups with weak hyperbolicity properties \nAbstract: In this talk\, we will discuss amenable action for groups\, which is a dynamical generalisation of amenability. Non-amenable groups like the Gromov hyperbolic groups\, relatively hyperbolic groups\, mapping class groups of surfaces and outer automorphism group of free groups\, admit amenable actions. The class of acylindrically hyperbolic groups is a generalisation of the above classes of groups. In this talk we will see on which spaces the above mentioned groups admits amenable actions and try to outline a proof of a general result that groups acting on a hyperbolic space with a WPD element\, admits a Borel amenable action on the Gromov boundary of the hyperbolic space. \nWe look forward to having you with us.

SUMMARY:Physics Colloquium
DESCRIPTION:Abstract: In the ΛCDM cosmological model the Universe is assumed to be isotropic and homogeneous when averaged on large scales. That the Cosmic Microwave Background has a dipole anisotropy is interpreted as due to our peculiar (non-Hubble) motion because of local inhomogeneity. There must then be a corresponding dipole in the sky distribution of sources at high redshift. Using catalogues of radio sources and quasars we find that this expectation is rejected at >5σ\, i.e. the distribution of distant matter is not isotropic in the 'CMB frame’. This calls into question the standard practice of boosting to this frame to analyse cosmological data\, in particular to infer acceleration of the Hubble expansion rate using Type Ia supernovae\, which is then interpreted as due to a Cosmological Constant Λ. We find that the inferred acceleration is anisotropic (in the direction of the CMB hotspot) and likely illusory because of our being embedded in a coherent bulk flow\, rather than due to dark energy.  \n[Background reading: The Cosmic Dipole Anomaly\, arXiv:2505.23526] \nAbout the Speaker: Professor Subir Sarkar is Professor Emeritus\, Department of Physics\, University of Oxford. He obtained his PhD (1982) at the Tata Institute of Fundamental Research\, Bombay. Since 1990\, Professor Sarkar has been at the Rudolf Peierls Centre for Theoretical Physics\, Oxford\, and served as Head of the Particle Theory Group (2011-19). He is now Professor Emeritus in Physics and Emeritus Fellow of Linacre College\, Oxford. \nProfessor Sarkar's research interests are at the interface of fundamental physics with astrophysics and cosmology (covering topics such as big bang nucleosynthesis\, dark matter\, dark energy\, inflation and the cosmic microwave background\, relic topological defects\, weak interactions and neutrinos etc). He also works on high energy cosmic rays\, gamma-rays and neutrinos\, and belongs to the IceCube Neutrino Observatory and the Cherenkov Telescope Array collaborations (previously he worked on the Pierre Auger Observatory for cosmic rays and the CERN BEBC Beam Dump neutrino experiment). \nProfessor Sarkar participates in laboratory experiments using high powered lasers to investigate astrophysical processes\, and programmes on Quantum Sensors for Fundamental Physics as well as the Legacy Survey of Space and Time on the Vera Rubin Observatory. He is keen to develop academic links with India and was a founder member of the India Oxford Initiative\, as well as coordinator of the Oxford-India Network in Theoretical Physical Sciences and long-time Senior Member of the Oxford India Society. \nWe look forward to your active participation.
