O Corona, where art thou? eROSITA's view of UV-optical-IR variability-selected massive black holes in low-mass galaxies
R. Arcodia, A. Merloni, J. Comparat +16
Finding massive black holes (MBHs, ) in the nuclei of low-mass galaxies () is crucial to constrain seeding and…
A versatile classification tool for galactic activity using optical and infrared colors
Charalampos Daoutis, Elias Kyritsis, Konstantinos Kouroumpatzakis +1
(abridged) The overwhelming majority of diagnostic tools for galactic activity are focused on active galaxies. Passive or dormant galaxies are often excluded from these diagnostics…
A versatile classification tool for galactic activity using optical and infrared colors
Elias Kyritsis, Charalampos Daoutis, Andreas Zezas +1
We use the Random Forest (RF) algorithm to develop a tool for automated activity classification of galaxies into 5 different classes: Star-forming (SF), AGN, LINER, Composite, and…
Star-formation rate and stellar mass calibrations based on infrared photometry and their dependence on stellar population age and extinction
Konstantinos Kouroumpatzakis, Andreas Zezas, Elias Kyritsis +2
The stellar mass () and the star-formation rate (SFR) are among the most important features that characterize galaxies. Measuring these fundamental properties accurately i…
