Persistent Emission Properties of SGR J1935+2154 During Its 2020 Active Episode

Ersin Gogus, Matthew G. Baring, Chryssa Kouveliotou +6

We present detailed spectral and temporal characteristics of the persistent X-ray emission of SGR J1935+2154 based on our XMM-Newton and Chandra observations taken in the aftermath…

PSR J1709-4429's Proper Motion and its Relationship to SNR G343.1-2.3

Martijn de Vries, Roger W. Romani, Oleg Kargaltsev +6

We have obtained a deep 670 ks CXO ACIS image of the remarkable pulsar wind nebula (PWN) of PSR J1709-4429, in 4 epochs during 2018-2019. Comparison with an archival 2004 data set…

A Minimal Time Scale for the Spectral States of GX 339-4

E. Sonbas, K. Mohamed, K. S. Dhuga +2

Black hole transients are known to undergo spectral transitions that form q-shaped tracks on a hardness intensity diagram. In this work, we use archival RXTE data to extract a char…

GRB Spectrum from Gradual Dissipation in a Magnetized Outflow

Ramandeep Gill, Jonathan Granot, Paz Beniamini

Modeling of gamma-ray burst (GRB) prompt emission spectra sometimes requires a (quasi-) thermal spectral component in addition to the Band function. In photospheric emission models…

Discovery of the optical afterglow and host galaxy of short GRB181123B at : Implications for Delay Time Distributions

K. Paterson, W. Fong, A. Nugent +19

We present the discovery of the optical afterglow and host galaxy of the {\it Swift} short-duration gamma-ray burst, GRB\,181123B. Observations with Gemini-North starting at $\appr…

A radiatively-quiet glitch and anti-glitch in the magnetar 1E 2259+586

G. Younes, P. S. Ray, M. G. Baring +5

We report on the timing and spectral properties of the soft X-ray emission from the magnetar 1E 2259+586 from January 2013, months after the detection of an anti-glitch, u…
