Old Galactic novae in the eROSITA All Sky Survey
Gloria Sala, Frank Haberl, Axel Schwope +4
Nova explosions occur on accreting white dwarfs. A thermonuclear runaway in the H-rich accreted envelope causes its ejection without destroying the white dwarf, and an increase in…
New high-z BL Lacs using the photometric method with Swift and SARA
Amanpreet Kaur, Arne Rau, Marco Ajello +5
BL Lacertae (BL Lac) objects are the prominent members of the third {\it Fermi} Large Area Telescope catalog of -ray sources. Half of the BL Lac population ( 300) lack red…
The supersoft X-ray source in V5116 Sgr I. The high resolution spectra
G. Sala, J. U. Ness, M. Hernanz +1
Classical novae occur on the surface of an accreting white dwarf in a binary system. After ejection of a fraction of the envelope and when the expanding shell becomes optically thi…
Discovery of a 0.42-s pulsar in the ultraluminous X-ray source NGC 7793 P13
G. L. Israel, A. Papitto, P. Esposito +11
NGC 7793 P13 is a variable (luminosity range ~100) ultraluminous X-ray source (ULX) proposed to host a stellar-mass black hole of less than 15 M in a binary system with o…
Correlated optical, X-ray, and gamma-ray flaring activity seen with INTEGRAL during the 2015 outburst of V404 Cygni
J. Rodriguez, M. Cadolle Bel, J. Alfonso-Garzón +20
After 25 years of quiescence, the microquasar V404 Cyg entered a new period of activity in June 2015. This X-ray source is known to undergo extremely bright and variable outbursts…
Investigating the nature of IGR J17454-2919 using X-ray and Near-Infrared observations
A. Paizis, M. A. Nowak, J. Rodriguez +7
IGR J17454-2919 is a hard X-ray transient discovered by INTEGRAL on 2014 September 27. We report on our 20ks Chandra observation of the source, performed about five weeks after the…
