Interpretation of Radio Afterglows in the framework of the Standard Fireball and Energy Injection models
Delina Levine, Maria Dainotti, Nissim Fraija +3
Gamma-Ray Bursts (GRBs) are panchromatic, highly energetic transients whose energy emission mechanism is still debated. One of the possible explanations is the standard fireball mo…
BASS XXXIX: Swift-BAT AGN with changing-look optical spectra
Matthew J. Temple, Claudio Ricci, Michael J. Koss +13
Changing-look (CL) AGN are unique probes of accretion onto supermassive black holes (SMBHs), especially when simultaneous observations in complementary wavebands allow investigatio…
The closure relations in optical afterglow of Gamma-Ray Bursts
M. G. Dainotti, D. Levine, D. Warren +2
Gamma-ray bursts (GRBs) are extremely high-energy events that can be observed at very high redshift. In addition to gamma rays, they can emit in X-ray, optical, and sometimes radio…

Radio-bright vs. Radio-dark Gamma-ray Bursts -- More Evidence for Distinct Progenitors
Angana Chakraborty, Maria Dainotti, Olivia Cantrell +1
We analyze two distinct samples of GRBs, with and without radio afterglow emission. We use a sample of 211 GRBs which is an update of the previous sample from arXiv:1902.01974, and…
The Gamma-ray Bursts fundamental plane correlation as a cosmological tool
M. G. Dainotti, A. Ł. Lenart, A. Chraya +5
Cosmological models and their corresponding parameters are widely debated because of the current discrepancy between the results of the Hubble constant, , obtained by SNe Ia…
The quest for new correlations in the realm of the Gamma-Ray Burst -- Supernova connection
M. G. Dainotti, B. De Simone, M. I. Khadir +5
Gamma-Ray Bursts (GRBs) are very energetic cosmological transients. Long GRBs are usually associated with Type Ib/c Supernovae (SNe), and we refer to them as GRB-SNe. Since the ass…
Phase-resolved spectroscopic analysis of the eclipsing black hole X-ray binary M33 X-7: System properties, accretion, and evolution
V. Ramachandran, L. M. Oskinova, W. -R. Hamann +10
M33 X-7 is the only known eclipsing black hole high mass X-ray binary. The system is reported to contain a very massive O supergiant donor and a massive black hole in a short orbit…
NuSTAR Observations of Intrinsically X-ray Weak Quasar Candidates: An Obscuration-Only Scenario
Chaojun Wang, B. Luo, W. N. Brandt +6
We utilize recent NuSTAR observations (co-added depth -120 ks) of PG , PG , and PHL 1811 to constrain their hard X-ray ( keV) weakness and…
Comment on "Nonideal Fields Solve the Injection Problem in Relativistic Reconnection"
Fan Guo, Xiaocan Li, Omar French +7
Recently, Sironi (PRL, 128, 145102; S22) reported the correlation between particles accelerated into high energy and their crossings of regions with electric field larger than magn…
A wind environment and Lorentz factors of tens explain gamma-ray bursts X-ray plateau
H. Dereli-Bégué, A. Pe'er, F. Ryde +3
Gamma-ray bursts (GRBs) are known to have the most relativistic jets, with initial Lorentz factors in the order of a few hundreds. Many GRBs display an early X-ray light-curve plat…

The Fermi Large Area Telescope (Fermi-LAT) Collaboration reported the Second Gamma-ray Burst Catalog (2FLGC), which comprises a subset of 29 bursts with photon energies above 10 Ge…
GRB Afterglow of the Sub-relativistic Materials with Energy Injection
N. Fraija, B. Betancourt Kamenetskaia, A. Galvan-Gamez +5
Sub-relativistic materials launched during the merger of binary compact objects and the core-collapse of massive stars acquire velocity structures when expanding in a stratified en…

Nissim Fraija, Antonio Galvan-Gamez, Boris Betancourt Kamenetskaia +5
Gamma-ray bursts (GRBs) are fascinating extragalactic objects. They represent a fantastic opportunity to investigate unique properties not exhibited in other sources. Multi-wavelen…
Localizing narrow Fe K emission within bright AGN
Carolina Andonie, Franz E. Bauer, Rosamaria Carraro +11
The 6.4 keV Fe Ka emission line is a ubiquitous feature in X-ray spectra of AGN, and its properties track the interaction between the variable primary X-ray continuum and the surro…
