The Optical Luminosity-Time Correlation for More Than 100 Gamma-Ray Burst Afterglows

M. G. Dainotti, S. Livermore, D. A. Kann +7

Gamma-Ray Bursts (GRBs) are fascinating events due to their panchromatic nature. Their afterglow emission is observed from sub-TeV energies to radio wavelengths. We investigate GRB…

The X-ray fundamental plane of the Platinum Sample, the Kilonovae and the SNe Ib/c associated with GRBs

Maria Giovanna Dainotti, Aleksander Lenart, Giuseppe Sarracino +3

A large fraction of Gamma-Ray Bursts (GRBs) lightcurves (LCs) shows X-ray plateaus. We analyze all GRBs with known redshifts presenting plateaus observed by \emph{The Neil Gehrels…

The Dynamics, Destruction, and Survival of Supernova-Formed Dust Grains

Jonathan D. Slavin, Eli Dwek, Mordecai-Mark Mac Low +1

Observations have demonstrated that supernovae efficiently produce dust. This is consistent with the hypothesis that supernovae and asymptotic giant branch stars are the primary pr…

On the investigation of the closure relations for Gamma-Ray Bursts observed by Swift in the post-plateau phase and the GRB fundamental plane

Gokul Prem Srinivasaragavan, Maria Giovanna Dainotti, Nissim Fraija +5

Gamma-Ray Bursts (GRBs) are the most explosive phenomena in the Universe after the Big Bang. A large fraction of GRB lightcurves (LCs) shows X-ray plateaus. We perform the most com…

Magnetic Energy Release, Plasma Dynamics, and Particle Acceleration during Relativistic Turbulent Magnetic Reconnection

Fan Guo, Xiaocan Li, William Daughton +5

In strongly magnetized astrophysical plasma systems, magnetic reconnection is believed to be a primary process during which explosive energy release and particle acceleration occur…

Observations of Four Nearby X-ray Faint AGN: Low Luminosity or Heavy Obscuration?

A. Annuar, D. M. Alexander, P. Gandhi +20

We present observations of four active galactic nuclei (AGN) located within 15 Mpc. These AGN, namely ESO 121-G6, NGC 660, NGC 3486 and NGC 5195, have observed X-ray lumin…

Constraining X-ray reflection in the low-luminosity AGN NGC 3718 using NuSTAR and XMM--Newton

Y. Diaz, P. Arévalo, L. Hernández-García +9

One distinctive feature of low-luminosity active galactic nuclei (LLAGN) is the relatively weak reflection features they may display in the X-ray spectrum, which can result from th…

GRB Fermi-LAT afterglows: explaining flares, breaks, and energetic photons

N. Fraija, T. Laskar, S. Dichiara +4

The Fermi-LAT collaboration presented the second gamma-ray burst (GRB) catalog covering its first 10 years of operations. A significant fraction of afterglow-phase light curves in…

Afterglow light curves of the non-relativistic ejecta mass in a stratified circumstellar medium

N. Fraija, B. Betancourt Kamenetskaia, M. G. Dainotti +4

We present the afterglow light curves produced by the deceleration of the non-relativistic ejecta mass in a stratified circumstellar medium with a density profile $n(r)\propto r^{-…
