The Star Formation Reference Survey-V: the effect of extinction, stellar mass, metallicity, and nuclear activity on star-formation rates based on H emission
Konstantinos Kouroumpatzakis, Andreas Zezas, Alexandros Maragkoudakis +5
We present new H photometry for the Star-Formation Reference Survey (SFRS), a representative sample of star-forming galaxies in the local Universe. Combining these data with the…
The Star Formation Reference Survey. IV. Stellar mass distribution of local star-forming galaxies
Paolo Bonfini, Andreas Zezas, Matthew L. N. Ashby +5
We constrain the mass distribution in nearby, star-forming galaxies with the Star Formation Reference Survey (SFRS), a galaxy sample constructed to be representative of all known c…
The Heraklion Extragalactic Catalogue (HECATE): a value-added galaxy catalogue for multi-messenger astrophysics
Konstantinos Kovlakas, Andreas Zezas, Jeff J. Andrews +6
We present the Heraklion Extragalactic Catalogue, or HECATE, an all-sky value-added galaxy catalogue, aiming to facilitate present and future multi-wavelength and multi-messenger s…
Metallicity and X-ray luminosity variations in NGC 922
Konstantinos Kouroumpatzakis, Andreas Zezas, Anna Wolter +3
We present a systematic study of the metallicity variations within the collisional ring galaxy NGC 922 based on long-slit optical spectroscopic observations. We find a metallicity…
Sub-galactic scaling relations between X-ray luminosity, star-formation rate, and stellar mass
Konstantinos Kouroumpatzakis, Andreas Zezas, Paul Sell +6
X-ray luminosity () originating from high-mass X-ray binaries (HMXBs) is tightly correlated with the host galaxy's star-formation rate (SFR). We explore this connection at sub…
Search for AGN counterparts of unidentified Fermi-LAT sources with optical polarimetry: Demonstration of the technique
N. Mandarakas, D. Blinov, I. Liodakis +12
The third Fermi-LAT catalog (3FGL) presented the data of the first four years of observations from the Fermi Gamma-ray Space Telescope mission. There are 3034 sources, 1010 of whic…
