Pulsed Infrared Emission from Magnetar 4U 0142+61 Detected by JWST
Jeremy Hare, George G. Pavlov, Bettina Posselt +3
We report on a JWST observation of the magnetar 4U 0142+61 on 2024 August 18 with the Near-Infrared Camera (NIRCam). NIRCam observed the magnetar for 33~min in timing mode, providi…
Science of High Resolution X-ray Imaging
H. L. Marshall, K. Weaver, M. Schattenburg +34
This report summarizes potential studies of the Hi-ReX Science Analysis Group for an Ultra-High Angular Resolution X-ray Observatory. Many potential science cases are presented, sp…
The Intermediate Mass Black Hole in Omega Centauri: Constraints on Accretion from JWST
Steven Chen, Jeremy Hare, Oleg Kargaltsev +4
We analyze JWST observations of the central region of the globular cluster Centauri (NGC 5139, Cen hereafter), around the position of the candidate IMBH inferred by \cite…
The nature of UHE source 1LHAASO J1740+0948u and its connection to PSR J1740+1000
Seth Gagnon, Yichao Lin, Alexander Lange +4
We present multi-wavelength analysis of 1LHAASO J1740+0948u and its surroundings including the pulsar wind nebula of middle-aged pulsar PSR J1740+1000. Although a dozen X-ray sourc…
Orbital Phase-resolved Analysis of X-ray and Gamma-ray Observations of the High-Mass Gamma-ray Binary 4FGL J1405.1-6119
Alexander Lange, Robin H. D. Corbet, Joel B. Coley +4
We present the results of multi-wavelength observations of the High-Mass Gamma-Ray Binary 4FGL J1405.1-6119. A pair of joint XMM-Newton and NuSTAR observations taken in 2019 (sampl…
Characterization of a peculiar Einstein Probe transient EP240408a: an exotic gamma-ray burst or an abnormal jetted tidal disruption event?
B. O'Connor, D. Pasham, I. Andreoni +30
We present the results of our multi-wavelength (X-ray to radio) follow-up campaign of the Einstein Probe transient EP240408a. The initial 10 s trigger displayed bright soft X-ray (…
