Mass Loss by X-ray Winds from Active Galactic Nuclei
Doron Chelouche
We consider a sample of type-I active galactic nuclei (AGN) that were observed by Chandra/HETG and resulted in high signal-to-noise grating spectra, which we study in detail. All o…

Spectroscopic Constraints on (pseudo-)Scalar Particles from Compact Astrophysical Objects
Doron Chelouche, Raul Rabadan, Sergey Pavlov +1
We propose a new method to search for light (pseudo-)scalar particles in the spectra of compact astrophysical objects such as magnetars, pulsars, and quasars. On accounts of compac…

On the HI content, dust-to-gas ratio and nature of MgII absorbers
Brice Ménard, Doron Chelouche
We estimate the mean dust-to-gas ratio of MgII absorbers as a function of rest equivalent width W_0 and redshift over the range 0.5<z<1.4. Using the expanded SDSS/HST sample of low…
