X-ray to Mid-IR Spectral Energy Distributions: A Catalog of X-ray Selected AGNs in the XMM-COSMOS Survey
Şeyda Şen, Eda Sonbas, Ece Kilerci +4
We present a component-resolved analysis of the IR--X-ray connection in a sample of 104 spectroscopically confirmed Type~1 AGN. By combining \xmm, \swift/UVOT, and new high--angula…
17 Yr of Magnetar Bursts Observed with the Fermi Gamma-ray Burst Monitor
Matt Godwin, Özge Keskin, Mustafa Demirer +17
The Fermi Gamma-ray Burst Monitor (GBM) has been in operation for over 17 years, during which it has observed more than a thousand bursts from soft gamma repeaters (SGRs), also kno…
Magnetar Fireballs and Short Bursts: Curved Spacetime Lensing, QED Effects, Spectra, Polarization, and Impulse Responses
Zorawar Wadiasingh, Hoa Dinh Thi, Constantinos Kalapotharakos +12
Magnetar short bursts (SBs) are hard X-ray transients of durations s peaking at keV, and are prime targets for new high-energy missions and polarimeters. The…
Resolving the 2024 Outburst of Magnetar 1E 1841-045 from its host Supernova Remnant with EP-FXT
Yu-Cong Fu, Lin Lin, Yu-Jia Zheng +11
The magnetar 1E 1841-045 exhibited a new active episode starting on August 20, 2024, marked by X-ray bursts and enhanced persistent emission. Using data from the Einstein Probe (EP…
A Combined TESS and Ground-based Study of Transit Timing Variations in HAT-P-16, TOI-1516 and TOI-2046 Systems
E. Sonbas, K. Kaplan, M. Tanriver +5
We present new results for the hot Jupiters HAT-P-16b, TOI-1516b, and TOI-2046b, based on photometric observations collected using both space- and ground-based facilities. Ground-b…
Correlation of Burst Behaviour with Magnetar Age
Ozge Keskin, Samuel K. Lander, Ersin Gogus
We analyze a wide set of historical magnetar burst observations detected with five different instruments, calibrating these to the energy range of Fermi-GBM observations for consis…
