SDSS low z quasar companion galaxies
D. Bettoni, R. Falomo, S. Paiano
We investigate the relationship between quasars and close companion galaxies using photometry and spectroscopy from the large data set of the SDSS DR16 survey. From the SDSS-QSO ca…
Investigating the nature of the ultraluminous X-ray sources in the galaxy NGC 925
Chiara Salvaggio, Anna Wolter, Fabio Pintore +7
Variability is a powerful tool to investigate properties of X-ray binaries (XRB), in particular for Ultraluminous X-ray sources (ULXs) that are mainly detected in the X-ray band. F…
