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…
The Large Deficit of HMXB Emission from Luminous Infrared Galaxies: the Case of the Circumnuclear Starburst Ring in NGC 7552
Lacey West, Kristen Garofali, Bret D. Lehmer +5
Luminous infrared galaxies (LIRGs), the most extreme star-forming galaxies in the nearby (D30 Mpc) Universe, show a notable X-ray emission deficiency (up to a factor of 10…
X-ray Binaries in External Galaxies
Marat Gilfanov, Giuseppina Fabbiano, Bret Lehmer +1
X-ray appearance of normal galaxies is mainly determined by X-ray binaries powered by accretion onto a neutron star or a stellar mass black hole. Their populations scale with the s…
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…
X-ray luminosity function of high-mass X-ray binaries: Studying the signatures of different physical processes using detailed binary evolution calculations
Devina Misra, Konstantinos Kovlakas, Tassos Fragos +11
The ever-expanding observational sample of X-ray binaries (XRBs) makes them excellent laboratories for constraining binary evolution theory. Such constraints can be obtained by stu…
