The Second Data Release of the Survey of the MAgellanic Stellar History (SMASH)
David L. Nidever, Knut Olsen, Yumi Choi +32
The Large and Small Magellanic Clouds (LMC and SMC) are the largest satellite galaxies of the Milky Way and close enough to allow for a detailed exploration of their structure and…
The ANTARES Astronomical Time-Domain Event Broker
Thomas Matheson, Carl Stubens, Nicholas Wolf +17
We describe the Arizona-NOIRLab Temporal Analysis and Response to Events System (ANTARES), a software instrument designed to process large-scale streams of astronomical time-domain…
Gravitational origin of dark matter and Majorana neutrino mass with non-minimal quartic inflation
Debasish Borah, Suruj Jyoti Das, Abhijit Kumar Saha
We propose a minimal framework to address successful quartic inflation, dark matter (DM) production in the early universe and non-vanishing tiny Majorana neutrino mass from a commo…
A dark clue to seesaw and leptogenesis in a pseudo-Dirac singlet doublet scenario with (non)standard cosmology
Partha Konar, Ananya Mukherjee, Abhijit Kumar Saha +1
We propose an appealing alternative scenario of leptogenesis assisted by dark sector which leads to the baryon asymmetry of the Universe satisfying all theoretical and experimental…
Cosmic Inflation in Minimal Model: Implications for (Non) Thermal Dark Matter and Leptogenesis
Debasish Borah, Suruj Jyoti Das, Abhijit Kumar Saha
We study the possibility of realising cosmic inflation, dark matter (DM), baryon asymmetry of the universe (BAU) and light neutrino masses in non-supersymmetric minimal gauged $B-L…
A classification algorithm for time-domain novelties in preparation for LSST alerts: Application to variable stars and transients detected with DECam in the Galactic Bulge
Monika D. Soraisam, Abhijit Saha, Thomas Matheson +8
With the advent of the Large Synoptic Survey Telescope (LSST), time-domain astronomy will be faced with an unprecedented volume and rate of data. Real-time processing of variables…
