Comprehensive X-ray Observations of the Exceptional Ultra-long X-ray and Gamma-ray Transient GRB 250702B with Swift, NuSTAR, and Chandra: Insights from the X-ray Afterglow Properties
Brendan O'Connor, Ramandeep Gill, James DeLaunay +22
GRB 250702B is an exceptional transient that produced multiple episodes of luminous gamma-ray radiation lasting for ks, placing it among the class of ultra-long gamma-ray bur…
A Temporal Scale to Track the Spectral Transitions in Low-Mass X-ray Binaries
E. Sonbas, K. Mohamed, K. S. Dhuga +1
The results of a temporal analysis of observations for a sample of nine low-mass X-ray binaries (LMXBs) are presented. Of these sources, five host a neutron star (NS) primary (4U16…
Probing Transit Timing Variations of Three Hot-Jupiters: HATP-36b, HATP-56b, and WASP-52b
E. Sonbas, N. Karaman, A. Özdönmez +5
We report the results of new transit observations for the three hot Jupiter-like planets HATP-36b, HATP-56b and WASP-52b respectively. Transit timing variations (TTVs) are presente…
A Minimal Timescale for the Continuum in 4U 1608-52 and Aql X-1
K. Mohamed, E. Sonbas, K. S. Dhuga +4
Similar to black-hole X-ray binary (BHXRB) transients, hysteresis-like state transitions are also seen in some neutron-star X-ray binaries (NSXRBs). Using a method based on wavelet…
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…
Broadband X-ray Burst Spectroscopy of the FRB-Emitting Galactic Magnetar
G. Younes, M. G. Baring, C. Kouveliotou +22
Magnetars are young, magnetically-powered neutron stars possessing the strongest magnetic fields in the Universe. Fast Radio Bursts (FRBs) are extremely intense millisecond-long ra…
Partial accretion in the propeller stage of low mass X-ray binary Aql X--1
Can Güngör, Kazım Yavuz Ekşi, Ersin Göğüş +1
Aql X--1 is one of the most prolific low mass X-ray binary transients (LMXBTs) showing outbursts almost annually. We present the results of our spectral analyses of RXTE/PCA observ…
GRB 130606A within a sub-DLA at redshift 5.91
A. J. Castro-Tirado, R. Sánchez-Ramírez, S. L. Ellison +38
Events such as GRB130606A at z=5.91, offer an exciting new window into pre-galactic metal enrichment in these very high redshift host galaxies. We study the environment and host ga…
