Retrieval of the physical parameters of galaxies from WEAVE-StePS-like data using machine learning

J. Angthopo, B. R. Granett, F. La Barbera +46

The WHT Enhanced Area Velocity Explorer (WEAVE) is a new, massively multiplexing spectrograph. This new instrument will be exploited to obtain high S/N spectra of 25000 galax…

Stellar metallicity from optical and UV spectral indices: Test case for WEAVE-StePS

F. R. Ditrani, M. Longhetti, F. La Barbera +35

The upcoming generation of optical spectrographs on four meter-class telescopes, with their huge multiplexing capabilities, excellent spectral resolution, and unprecedented wavelen…

Non-gaussianity of optical emission lines in SDSS star-forming galaxies and its implications on galactic outflows

B. P. Brian Yu, James Angthopo, Ignacio Ferreras +1

The shape of emission lines in the optical spectra of star-forming galaxies reveals the kinematics of the diffuse gaseous component. We analyse the shape of prominent emission line…

Testing the role of AGN on the star formation and metal enrichment of "twin galaxies"

J. Angthopo, I. del Moral-Castro, I. Ferreras +2

We explore the effect of AGN activity on the star formation history of galaxies by analysing the stellar population properties of ten pairs of nearby twin galaxies -- selected as b…

Evaluating hydrodynamical simulations with green valley galaxies

J. Angthopo, A. Negri, I. Ferreras +3

We test cosmological hydrodynamical simulations of galaxy formation regarding the properties of the Blue Cloud (BC), Green Valley (GV) and Red Sequence (RS), as measured on the 400…
