Accounting for Selection Bias and Redshift Evolution in GRB Radio Afterglow Data

Maria Dainotti, Delina Levine, Nissim Fraija +1

Gamma-ray Bursts (GRBs) are highly energetic events that can be observed at extremely high redshift. However, inherent bias in GRB data due to selection effects and redshift evolut…

Examining Two-Dimensional Luminosity-time Correlations for Gamma Ray Burst Radio Afterglows with VLA and ALMA

Delina Levine, Maria Dainotti, Kevin J. Zvonarek +4

Gamma-ray burst (GRB) afterglow emission can be observed from sub-TeV to radio wavelengths, though only 6.6\% of observed GRBs present radio afterglows. We examine GRB radio light…

A semi-analytic afterglow with thermal electrons and synchrotron self-Compton emission

Donald C. Warren, Maria Dainotti, Maxim V. Barkov +3

We extend previous work on gamma-ray burst (GRB) afterglows involving hot thermal electrons at the base of a shock-accelerated tail. Using a physically-motivated electron distribut…

A theoretical model of an off-axis GRB jet

B. Betancourt Kamenetskaia, N. Fraija, M. Dainotti +3

In light of the most recent observations of late afterglows produced by the merger of compact objects or by the core-collapse of massive dying stars, we research the evolution of t…

Predicting the redshift of gamma-ray loud AGNs using supervised machine learning

Maria Giovanna Dainotti, Malgorzata Bogdan, Aditya Narendra +8

AGNs are very powerful galaxies characterized by extremely bright emissions coming out from their central massive black holes. Knowing the redshifts of AGNs provides us with an opp…

Physically motivated X-ray obscurer models

Johannes Buchner, Murray Brightman, Mislav Baloković +3

The nuclear obscurer of Active Galactic Nuclei (AGN) is poorly understood in terms of its origin, geometry and dynamics. We investigate whether physically motivated geometries emer…

Closure relations during the plateau emission of Swift GRBs and the fundamental plane

M. G. Dainotti, A. Ł. Lenart, N. Fraija +5

The Neil Gehrels Swift observatory observe Gamma-Ray bursts (GRBs) plateaus in X-rays. We test the reliability of the closure relations through the fireball model when dealing with…

On the Existence of the Plateau Emission in High-Energy Gamma-Ray Burst LightCurves observed byFermi-LAT

Maria Giovanna Dainotti, Nicola Omodei, Gokul . P. Srinivasaragavan +10

The Large Area Telescope (LAT) on board the \Fermi Gamma-ray Space Telescope (\Fermi) shows long-lasting high-energy emission in many gamma-ray bursts (GRBs), similar to X-ray afte…

Cosmological Evolution of the Formation Rate of Short Gamma-ray Bursts With and Without Extended Emission

Maria Giovanna Dainotti, Vahe' Petrosian, Luke Bowden

Originating from neutron star-neutron star (NS-NS) or neutron star-black hole (NS-BH) mergers, short gamma-ray bursts (SGRBs) are the first electromagnetic emitters associated with…

BAT AGN Spectroscopic Survey XXVII: Scattered X-Ray Radiation in Obscured Active Galactic Nuclei

K. K. Gupta, C. Ricci, A. Tortosa +20

Accreting supermassive black holes (SMBHs), also known as active galactic nuclei (AGN), are generally surrounded by large amounts of gas and dust. This surrounding material reproce…
