Detecting Axion-like particles using Cosmic Variance Cancellation with CMB and Radio surveys
Harsh Mehta, Anaya Dixit, Suvodip Mukherjee +1
Axions and axion-like particles (ALPs) arise naturally in many extensions of the Standard Model and are among the well-motivated candidates for dark matter. In the presence of magn…
Modified Cosmology or Modified Galaxy Astrophysics is Driving the z>6 JWST Results? CMB Experiments can discover the Origin in the Near Future
Harsh Mehta, Suvodip Mukherjee
The massive and bright galaxies observed by the James Webb Space Telescope (JWST) at high redshifts () have challenged our understanding of the Universe. This may require re…
The Prospect from the Upcoming CMB Experiment LiteBIRD to Discover Axion-like Particles Using Milky Way
Harsh Mehta, Suvodip Mukherjee
The existence of axion-like particles (ALPs) can be probed from their signatures in the Cosmic Microwave Background (CMB) due to the photon-ALP resonant conversion over the mass ra…
A White Paper on The Multi-Messenger Science Landscape in India
Samsuzzaman Afroz, Sanjib Kumar Agarwalla, Dipankar Bhattacharya +35
The multi-messenger science using different observational windows to the Universe such as Gravitational Waves (GWs), Electromagnetic Waves (EMs), Cosmic Rays (CRs), and Neutrinos o…
Turbulence Induced Non-Gaussian Spectral Distortion in the Microwave Sky from Photon-Axion Conversion in Galaxy Clusters
Harsh Mehta, Suvodip Mukherjee
The conversion of CMB photons to axions (or axion-like particles (ALPs)) can lead to a unique spectral distortion in the temperature and polarization sky which can be explored in u…
SpectrAx: Spectral Search of Axion-Like Particles Using Multi-Band Observations of Galaxy Clusters from SKA, SO, CMB-S4 and eROSITA
Harsh Mehta, Suvodip Mukherjee
The existence of axions or Axion-Like Particles (ALPs) has been predicted by various Beyond Standard Model (BSM) theories, and the proposed photon-ALP interaction is one of the way…
