Shining LIMelight into the dark: Probing Dark matter - baryon interactions with Line Intensity Mapping
Durba Ghosh, Ranjini Mondol, Ranjan Laha
Line-intensity mapping (LIM) is an emerging technique for probing both the astrophysics of galaxy formation and the cosmological evolution of large-scale structure. We investigate,…
Not so good s for Higgsino dark matter as LZ excess: stringent limits from Super-Kamiokande and IceCube
Debajit Bose, Akash Kumar Saha, Deep Jyoti Das +9
The LUX-ZEPLIN (LZ) collaboration has recently reported a single nuclear recoil event at a high recoil energy of about 250 keV. This has been interpreted as inelastic scattering of…
Dark Secrets of Baryons: Illuminating Dark Matter-Baryon Interactions with JWST
Souradeep Das, Ranjini Mondol, Abhijeet Singh +1
The James Webb Space Telescope (JWST) has discovered bright galaxies at high redshifts () and various galaxy candidates extending to even higher redshifts ($z\appro…
Road through Darkess: Probing dark matter-neutrino interactions using KM3-230213A
Ranjini Mondol, Subhadip Bouri, Akash Kumar Saha +1
KM3NeT has recently reported an event where a muon of energy PeV was observed at its ARCA detector, which can stem from a very high-energy neutrino interaction i…
Young Black Holes Have Smooth Horizons: A Swampland Argument
Chethan Krishnan, Ranjini Mondol
It has been suggested that black hole microstates in string theory may have "no interiors". The arguments of arXiv:2312.14108 suggest that even if this were the case, conventional…
Big Bang in Dipole Cosmology
A. Allahyari, E. Ebrahimian, R. Mondol +1
We continue the study of dipole cosmology framework put forward in \cite{Krishnan:2022qbv}, a beyond FLRW setting that has a preferred direction in the metric which may be associat…
Towards A Realistic Dipole Cosmology: The Dipole CDM Model
Ehsan Ebrahimian, Chethan Krishnan, Ranjini Mondol +1
Dipole cosmology is the maximally Copernican generalization of the FLRW paradigm that can incorporate bulk flows in the cosmic fluid. In this paper, we first discuss how multiple f…
A Tilt Instability in the Cosmological Principle
Chethan Krishnan, Ranjini Mondol, M. M. Sheikh-Jabbari
We show that the Friedmann-Lemaître-Robertson-Walker (FLRW) framework has an instability towards the growth of fluid flow anisotropies, even if the Universe is accelerating. This f…
Dipole Cosmology: The Copernican Paradigm Beyond FLRW
Chethan Krishnan, Ranjini Mondol, M. M. Sheikh-Jabbari
We introduce the , the idea that the Universe is a maximally Copernican cosmology, compatible with a cosmic flow. It serves as the most symmetric…
as a Universal FLRW Diagnostic
Chethan Krishnan, Ranjini Mondol
We reverse the logic behind the apparent existence of -tension, to design diagnostics for cosmological models. The basic idea is that the non-constancy of inferred from…
