The differences between mass- and light-derived structural parameters over time for MaNGA Elliptical galaxies
H. Ibarra-Medel, V. Avila-Reese, I. Lacerna +4
We apply stellar population synthesis analysis to obtain spatially-resolved archaeological inferences for a large sample of "red and dead" Elliptical galaxies (Classical Elliptical…
The galaxy HI-(sub)halo connection and the HI spatial clustering of local galaxies
A. R. Calette, Aldo Rodríguez-Puebla, Vladimir Avila-Reese +1
We extend the local stellar galaxy-(sub)halo connection to the atomic hydrogen (HI) component by seeding semi-empirically galaxies into a large N-body dark matter (DM) simulation.…
The HI and stellar mass bivariate distribution of centrals and satellites for all, late- and early-type local galaxies
A. R. Calette, Vladimir Avila-Reese, Aldo Rodríguez-Puebla +2
We characterize the conditional distributions of the HI gas-to-stellar mass ratio, , given the stellar mass, , of local galaxies from $M_{\a…
The evolution of compact massive quiescent and starforming galaxies derived from the and relations
L. Zanisi, F. Shankar, H. Fu +12
The mean size ( effective radius ) of Massive Galaxies (MGs, ) is observed to increase steadily with cosmic time. It is still unclear whether th…
Size, shade or shape? The contribution of galaxies of different types to the star-formation history of the Universe from SDSS-IV MaNGA
Thomas Peterken, Alfonso Aragón-Salamanca, Michael Merrifield +7
By fitting stellar populations to SDSS-IV MaNGA survey observations of ~7000 suitably-weighted individual galaxies, we reconstruct the star-formation history of the Universe, which…
HI-MaNGA: Tracing the physics of the neutral and ionized ISM with the second data release
David V. Stark, Karen L. Masters, Vladimir Avila-Reese +19
We present the second data release for the HI-MaNGA programme of HI follow-up observations for the SDSS-IV MaNGA survey. This release contains measurements for 3669 unique galaxies…
