Probing evolution of Long GRB properties through their cosmic formation history aided by Machine Learning predicted redshifts
Dhruv S. Bal, Aditya Narendra, Maria Giovanna Dainotti +3
Gamma-ray Bursts (GRBs) are valuable probes of cosmic star formation reaching back into the epoch of reionization, and a large dataset with known redshifts () is an important in…
Probing Evolution of Long Gamma-Ray Burst Properties through Their Cosmic Formation History
Nikita S. Khatiya, Maria Giovanna Dainotti, Aditya Narendra +3
The astrophysics of Long GRB (LGRB) progenitors as well as possible cosmological evolution in their properties still poses many open questions. Previous studies suggest that the LG…
Gamma-Ray Bursts as an Independent High-Redshift Probe of Dark Energy
Maria Giovanna Dainotti, Aleksander Åukasz Lenart, Biagio De Simone +6
Testing the CDM model requires cosmological probes spanning the wide redshift interval between Type Ia Supernovae (SNe Ia, ) and the Cosmic Microwave Background (…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
GRB Redshift Estimation using Machine Learning and the Associated Web-App
Aditya Narendra, Maria Dainotti, Milind Sarkar +7
Context. Gamma-ray bursts (GRBs), observed at redshifts as high as 9.4, could serve as valuable probes for investigating the distant Universe. However, this necessitates an increas…
The multiwavelength correlations quest for central engines of GRB plateaus: magnetar vs black hole spin-down
Aleksander Å. Lenart, Maria G. Dainotti, Nikita Khatiya +4
This manuscript presents a multilevel analysis of gamma-ray bursts (GRBs). We focus on the plateau phase, which is often observed in the light curves (LCs) of GRBs. We discuss its…
