Search for transient gamma-ray emission from magnetar flares using Fermi-LAT
Vyaas Ramakrishnan, Shantanu Desai
We search for transient gamma-ray emission in the energy range from 0.1-10 GeV using data from the Fermi-LAT telescope in coincidence with magnetar flares. For our analysis, we loo…
Search for spatial coincidence between IceCube neutrinos and gamma-ray bright red dwarfs
Fathima Shifa M, Shantanu Desai
We search for a spatial coincidence between high energy neutrinos detected by the IceCube neutrino detector and ten red dwarfs which have been observed in gamma-rays. For our analy…
Search for GeV gamma-ray emission from SPT-CL J2012-5649 with six years of DAMPE data
Siddhant Manna, Shantanu Desai
We search for gamma-ray emission from the galaxy cluster SPT-CL J2012-5649 in the energy range from 3 GeV to 1 TeV using the DArk Matter Particle Explorer (DAMPE) telescope. For ou…
Search for MeV Gamma-ray emission from TeV bright red dwarfs with COMPTEL
Niharika Shrivastava, Siddhant Manna, Shantanu Desai
The SHALON atmospheric Cherenkov telescope has detected very high energy gamma-ray emission at TeV energies from eight red dwarfs, namely, V388 Cas, V547 Cas, V780 Tau, V962 Tau, V…
Search for Dark Matter Annihilation to gamma-rays from SPT-SZ selected Galaxy Clusters
Siddhant Manna, Shantanu Desai
We search for dark matter annihilation from galaxy clusters in the energy range from 1-300 GeV using nearly 16 years of Fermi-LAT data. For this purpose, we use 350 galaxy clusters…
A test for the redshift dependence of using measurements
Siddhant Manna, Shantanu Desai
We search for a redshift dependence of using 23 growth rate measurements from redshift space distortions and peculiar velocity measurements as a consistency check of CDM…
Tully-Fisher Relation of Late-type Galaxies at
Gauri Sharma, Varenya Upadhyaya, Paolo Salucci +1
We present a study of the stellar and baryonic Tully-Fisher relation within the redshift range of utilizing observations of \sfgs. This dataset, as explored i…
A study of gamma-ray emission from OJ 287 using Fermi-LAT from 2015-2023
Vibhavasu Pasumarti, Shantanu Desai
We search for gamma-ray emission from OJ287 in the energy range from 0.1-300 GeV during 2015-2023, in coincidence with an extensive observing campaign to monitor the optical flux v…
The Gravitational Lensing Imprints of DES Y3 Superstructures on the CMB: A Matched Filtering Approach
Umut Demirbozan, Seshadri Nadathur, Ismael Ferrero +63
Low density cosmic voids gravitationally lens the cosmic microwave background (CMB), leaving a negative imprint on the CMB convergence . This effect provides insight into the…
Generalized Lomb-Scargle Analysis of 22 years of Super-Kamiokande solar B neutrino data
Vibhavasu Pasumarti, Shantanu Desai
We apply the generalized Lomb-Scargle periodogram to 22 years data of solar B neutrino fluxes detected by Super-Kamiokande. The primary motivation of this work was to check i…
A pilot search for MeV gamma-ray emission from five galaxy clusters using archival COMPTEL data
Siddhant Manna, Shantanu Desai
We search for MeV gamma-ray emission between 0.75-30 MeV from five galaxy clusters, viz. Coma, VIRGO, SPT-CL J2012-5649, Bullet, and El Gordo, using archival data from the COMPTEL…
