Cosmic evolution of molecular gas mass density from an empirical relationship between L1.4 GHz and L' CO

Orellana González, Gustavo; Ibar, E.; Leiton, R.; Thomson, A. P.; Cheng, C.; Ivison, R. J; Herrera Camus, R.; Messias, H.; Calderon Castillo, P.; Hughes, T. M.; Leeuw, L. (2020-06)

Historically, GHz radio emission has been used extensively to characterize the star-formation activity in galaxies. In this work, we look for empirical relationships amongst the radio luminosity, the infrared luminosity, ...
The evolution of brightest cluster galaxies in the nearby Universe II: The star-formation activity and the stellar mass from spectral energy distribution

Orellana-González, G.; Cerulo, P.; Covone, G.; Cheng, C.; Leiton, R.; Demarco, R.; Gendron-Marsolais, M.-L. (2022)

We study the star-formation activity in a sample of ∼ 56 000 brightest cluster galaxies (BCGs) at 0.05 < z < 0.42 using optical and infra-red data from SDSS and WISE. We estimate stellar masses and star-formation rates ...
