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…
Probing the origin of the extended flaring branch of Z-type X-ray binaries GX 340+0 and GX 5-1 using AstroSat
Tanmoy Dutta, Mayukh Pahari, Anish Sarkar +2
`Z' type neutron star low-mass X-ray binaries typically show a `Z'-like three-branched track in their hardness intensity diagram. However, a few such `Z' sources show an additional…
Constraint on Lorentz Invariance Violation for spectral lag transition in GRB 160625B using profile likelihood
Shantanu Desai, Shalini Ganguly
We reanalyze the spectral lag data for GRB 160625B using frequentist inference in order to constrain the energy scale () of Lorentz Invariance Violation (LIV). For this pur…
X-ray and Radio Campaign of the Z-source GX 340+0 II: the X-ray polarization in the normal branch
Yash Bhargava, Thomas D. Russell, Mason Ng +11
We present the first X-ray polarization measurement of the neutron star low-mass X-ray binary and Z-source, GX 3400, in the normal branch (NB) using a 200 ks observation with th…
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…
Effect of Magnetic Field on the Formation of Radiatively Inefficient Accretion Flow around Black Holes
Anish Sarkar, Mayukh Pahari
We study the effects of magnetic field in the formation of a radiatively inefficient accretion flow (RIAF) in the presence of Bremsstrahlung cooling, which facilitates the formatio…
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…
The ORT and the uGMRT Pulsar Monitoring Program : Pulsar Timing Irregularities & the Gaussian Process Realization
Himanshu Grover, Bhal Chandra Joshi, Jaikhomba Singha +8
The spin-down law of pulsars is generally perturbed by two types of timing irregularities: glitches and timing noise. Glitches are sudden changes in the rotational frequency of pul…
Calibration of luminosity correlations of gamma-ray bursts using quasars
Sarveshkumar Purohit, Shantanu Desai
In order to test the efficacy of Gamma-ray Bursts (GRB) as cosmological probes, we characterize the scatter in the correlations between six pairs of GRB observables, which have pre…
AstroSat and NICER timing view of the Z-type Neutron Star X-ray binary GX 340+0
Mayukh Pahari, Shree Suman, Yash Bhargava +5
The timing properties of the Z-type low-mass X-ray binaries provide insights into the emission components involved in producing the unique Z-shaped track in the hardness-intensity…
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…
