Shocks in the outflow of the RS Oph 2021 eruption observed with X-ray gratings
Marina Orio, Ehud Behar, Juan Luna +9
The 2021 outburst of the symbiotic recurrent nova RS Oph was observed with the Chandra High Energy Transmission Gratings (HETG) on day 18 after optical maximum and with XMM-Newton…
Discovery of the most luminous quasar of the last 9 Gyr
Christopher A. Onken, Samuel Lai, Christian Wolf +8
We report the discovery of a bright (g = 14.5 mag (AB), K = 11.9 mag (Vega)) quasar at redshift z = 0.83 -- the optically brightest (unbeamed) quasar at z > 0.4. SMSS J114447.77-43…
Breaking the degeneracy in magnetic cataclysmic variable X-ray spectral modeling using X-ray light curves
Diogo Belloni, Claudia V. Rodrigues, Matthias R. Schreiber +12
We present an analysis of mock X-ray spectra and light curves of magnetic cataclysmic variables using an upgraded version of the 3D CYCLOPS code. This 3D representation of the accr…
X-ray Spectra and Light Curves of Cooling Novae and a Nova-Like
Bangzheng Sun, Marina Orio, Andrej Dobrotka +3
We present X-ray observations of novae V2491 Cyg and KT Eri about 9 years post-outburst, of the dwarf nova and post-nova candidate EY Cyg, and of a VY Scl variable. The first three…
Optical spectroscopy and X-ray observations of the D-type symbiotic star EF Aql
K. A. Stoyanov, K. Iłkiewicz, G. J. M. Luna +6
We performed high-resolution optical spectroscopy and X-ray observations of the recently identified Mira-type symbiotic star EF Aql. Based on high-resolution optical spectroscopy o…
Chandra High Energy Transmission Gratings Spectra of V3890 Sgr
Marina Orio, Jeremy J. Drake, Jan-Uwe Ness +13
The recurrent nova (RN) V3890 Sgr was observed during the 7th day after the onset of its most recent outburst, with the Chandra ACIS-S camera and High Energy Transmission Gratings…
