HECATEv2: An all-sky galaxy catalogue for multimessenger astrophysics
E. Kyritsis, A. Zezas, K. Kovlakas +4
We present HECATEv2, the second release of the Heraklion Extragalactic Catalogue (HECATE), an all-sky, value-added galaxy catalogue comprising 204733 galaxies from the HyperLEDA da…
Mid-Infrared diagnostics for identifying main sequence galaxies in the local Universe
C. Daoutis, A. Zezas, M. L. N. Ashby
A galaxy's mid-IR spectrum encodes key information on its radiation field, star formation, and dust properties. Characterizing this spectrum therefore offers strong constraints on…
From seagull to hummingbird: New diagnostic methods for resolving galaxy activity
C. Daoutis, A. Zezas, E. Kyritsis +2
Context. A major challenge in astrophysics is classifying galaxies by their activity. Current methods often require multiple diagnostics to capture the full range of galactic activ…
Blueberry galaxies up to 200 Mpc and their optical and infrared properties
K. Kouroumpatzakis, J. Svoboda, A. Zezas +6
Dwarf highly star-forming galaxies (SFGs) dominated the early Universe and are considered the main driver of its reionization. However, direct observations of these distant galaxie…
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…
