The major merger-active galactic nucleus connection up to the cosmic noon
A. La Marca, B. Margalef-Bentabol, L. Wang +3
Galaxy major mergers are a potential mechanism for triggering active galactic nuclei (AGN) activity, but their role remains debated, particularly beyond the local Universe. We aim…
WEAVE imaging spectroscopy of NGC 6720: an iron bar in the Ring
R. Wesson, J. E. Drew, M. J. Barlow +23
We present spatially resolved spectroscopic observations of the planetary nebula NGC 6720, the Ring Nebula, taken during the science verification phase of WEAVE, a new instrument m…
Galactic bars and active galactic nucleus fuelling in the second half of cosmic history
A. La Marca, M. T. Nardone, L. Wang +3
We investigate the role of galactic bars in fuelling and triggering Active Galactic Nucleus (AGN) in disc galaxies up to . We utilise a Deep Learning model, fine-tuned o…
WEAVE First Light Observations: Origin and Dynamics of the Shock Front in Stephan's Quintet
M. I. Arnaudova, S. Das, D. J. B. Smith +62
We present a detailed study of the large-scale shock front in Stephan's Quintet, a byproduct of past and ongoing interactions. Using integral-field spectroscopy from the new Willia…
Dust and Power: Unravelling the merger - active galactic nucleus connection in the second half of cosmic history
A. La Marca, B. Margalef-Bentabol, L. Wang +8
Galaxy mergers represent a fundamental physical process under hierarchical structure formation, but their role in triggering AGNs is still unclear. We aim to investigate the merger…
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…
Diagnosing the interstellar medium of galaxies with far-infrared emission lines I. The [C II] 158 microns line at z~0
Andrés Felipe Ramos Padilla, Lingyu Wang, Sylvia Ploeckinger +2
Atomic fine structure lines have been detected in the local Universe and at high redshifts over the past decades. The [C II] emission line at 158 m is an important observable as…
IMF shape constraints from stellar populations and dynamics from CALIFA
M. Lyubenova, I. Martín-Navarro, G. van de Ven +22
In this letter we describe how we use stellar dynamics information to constrain the shape of the stellar IMF in a sample of 27 early-type galaxies from the CALIFA survey. We obtain…
The non-universality of the low-mass end of the IMF is robust against the choice of SSP model
Chiara Spiniello, Scott C. Trager, Léon V. E. Koopmans
We perform a direct comparison of two state-of-the art single stellar population (SSP) models that have been used to demonstrate the non-universality of the low-mass end of the Ini…
Galactic chemical evolution in hierarchical formation models - I. Early-type galaxies in the local Universe
Matías Arrigoni, Scott C. Trager, Rachel S. Somerville +1
We study the metallicities and abundance ratios of early-type galaxies in cosmological semi-analytic models (SAMs) within the hierarchical galaxy formation paradigm. To achieve thi…
The Stellar Population Histories of Early-Type Galaxies. II. Controlling Parameters of the Stellar Populations
S. C. Trager, S. M. Faber, G. Worthey +1
We analyze single-stellar-population (SSP) equivalent parameters for 50 local elliptical galaxies as a function of their structural parameters. These galaxies fill a two-dimensiona…
