A Detailed Spectral Study of Intermittent-Accreting Millisecond X-ray Pulsar Aql X-1 during Pulse-on and Pulse-off Stages
T. Kocabıyık, C. Güngör, M. T. Sağlam +2
We present a detailed spectral study of an intermittent-AMXP Aql X-1 during the pulse-on and pulse-off stages by using the archival RXTE data. We first perform temporal analysis by…
Broadband time-resolved spectroscopy of thermonuclear X-ray bursts from 4U 1636-536 using AstroSat
Unnati Kashyap, Biki Ram, Tolga Guver +1
Broadband spectral studies of Type-I X-ray bursts can put strong constraints on the physics of burst spectra as well as their interaction with the environment. We present the resul…
Variable Absorption Line in XTE J1810-197
Eda Vurgun, Manoneeta Chakraborty, Tolga Güver +1
We report the results of a long-term spectral and timing study of the first transient magnetar, XTE J1810-197 which was discovered in 2003 when its X-ray luminosity increased 100 f…
The mass and the radius of the neutron star in the transient low mass X-ray binary SAX J1748.9-2021
Tolga Guver, Feryal Ozel
We use time resolved spectroscopy of thermonuclear X-ray bursts observed from SAX J1748.9-2021 to infer the mass and the radius of the neutron star in the binary. Four X-ray bursts…
Looking Into the Fireball: ROTSE-III and Swift Observations of Early GRB Afterglows
E. S. Rykoff, F. Aharonian, C. W. Akerlof +21
We report on a complete set of early optical afterglows of gamma-ray bursts (GRBs) obtained with the ROTSE-III telescope network from March 2005 through June 2007. This set is comp…
