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…
Towards discovery of gravitationally lensed explosive transients: the brightest galaxies in massive galaxy clusters from Planck-SZ2
Joshua C. Smith, Dan Ryczanowski, Matteo Bianconi +7
We combine the Planck-SZ2 galaxy cluster catalogue with near-infrared photometry of galaxies from the VISTA Hemisphere Survey to identify candidate brightest cluster galaxies (BCGs…
WEAVE-StePS. A stellar population survey using WEAVE at WHT
A. Iovino, B. M. Poggianti, A. Mercurio +44
The upcoming new generation of optical spectrographs on four-meter-class telescopes will provide valuable opportunities for forthcoming galaxy surveys through their huge multiplexi…
On the gravitational lensing interpretation of three gravitational wave detections in the mass gap by LIGO and Virgo
Matteo Bianconi, Graham P. Smith, Matt Nicholl +7
We search for gravitational wave (GW) events from LIGO-Virgo's third run that may have been affected by gravitational lensing. Gravitational lensing delays the arrival of GWs, and…
Preparing for low surface brightness science with the Vera C. Rubin Observatory: characterisation of tidal features from mock images
G. Martin, A. E. Bazkiaei, M. Spavone +50
Tidal features in the outskirts of galaxies yield unique information about their past interactions and are a key prediction of the hierarchical structure formation paradigm. The Ve…
Pilot-WINGS: An extended MUSE view of the structure of Abell 370
David J. Lagattuta, Johan Richard, Franz Erik Bauer +18
We investigate the strong-lensing cluster Abell 370 (A370) using a wide Integral Field Unit (IFU) spectroscopic mosaic from the Multi-Unit Spectroscopic Explorer (MUSE). IFU spectr…
Extensive Lensing Survey of Optical and Near-Infrared Dark Objects (El Sonido): HST H-Faint Galaxies behind 101 Lensing Clusters
Fengwu Sun, Eiichi Egami, Pablo G. Pérez-González +22
We present a Spitzer/IRAC survey of H-faint (, ) sources in 101 lensing cluster fields. Across a CANDELS/Wide-like survey area of 648 arcmin (e…
LoCuSS: The splashback radius of massive galaxy clusters and its dependence on cluster merger history
Matteo Bianconi, Riccardo Buscicchio, Graham P. Smith +4
We present the direct detection of the splashback feature using the sample of massive galaxy clusters from the Local Cluster Substructure Survey (LoCuSS). This feature is clearly d…
On building a cluster watch-list for identifying strongly lensed supernovae, gravitational waves and kilonovae
Dan Ryczanowski, Graham P. Smith, Matteo Bianconi +3
Motivated by discovering strongly-lensed supernovae, gravitational waves, and kilonovae in the 2020s, we investigate whether to build a watch-list of clusters based on observed clu…
LoCuSS: exploring the connection between local environment, star formation and dust mass in Abell 1758
Matteo Bianconi, Graham P. Smith, Chris P. Haines +3
We explore the connection between dust and star formation, in the context of environmental effects on galaxy evolution. In particular, we exploit the susceptibility of dust to exte…
LoCuSS: Pre-processing in galaxy groups falling into massive galaxy clusters at z=0.2
Matteo Bianconi, Graham P. Smith, Chris P. Haines +3
We report direct evidence of pre-processing of the galaxies residing in galaxy groups falling into galaxy clusters drawn from the Local Cluster Substructure Survey (LoCuSS). 34 gro…
SCUBA-2 follow-up of Herschel-SPIRE observed Planck overdensities
Todd P. MacKenzie, Douglas Scott, Matteo Bianconi +11
We present SCUBA-2 follow-up of 61 candidate high-redshift Planck sources. Of these, 10 are confirmed strong gravitational lenses and comprise some of the brightest such submm sour…
Star formation and black hole accretion activity in rich local clusters of galaxies
Matteo Bianconi, Francine Marleau, Dario Fadda
We present a study of the star formation and central black hole accretion activity of the galaxies hosted in the two nearby (z0.2) rich galaxy clusters Abell 983 and 1731. Ai…
Infrared signature of active massive black holes in nearby dwarf galaxies
Francine R. Marleau, Dominic Clancy, Rebecca Habas +1
We investigate the possible presence of active galactic nuclei (AGN) in dwarf galaxies and other nearby galaxies to identify candidates for follow-up confirmation and dynamical mas…
