High-Redshift Starbursting Dwarf Galaxies Revealed by γ-Ray Burst Afterglows
(2009)
We present a study of 15 long-duration γ-ray burst (GRB) host galaxies at z > 2. The GRBs are selected with available early-time afterglow spectra in order to compare interstellar medium (ISM) absorption-line properties ...
Accretion of galaxy groups into galaxy clusters
(Wiley Blackwell Publishing, Inc, 2020-11)
We study the role of group infall in the assembly and dynamics of galaxy clusters in ΛCDM. We select 10 clusters with virial mass M200 ∼1014 M from the cosmological hydrodynamical simulation Illustris and follow their ...
AGN spiral galaxies in groups: effects of bars
(EDP Sciences, 2014-12)
AIMS: We explore properties of barred active spiral galaxies in groups and clusters selected from the Sloan Digital Sky Survey data release 7 (SDSS-DR7), with the aim of assessing the effects of bars on active galactic ...
A young stellar environment for the superluminous supernova PTF12dam
(OXFORD UNIV PRESS, 2015)
The progenitors of superluminous supernovae (SLSNe) are still a mystery. Hydrogen-poor SLSN hosts are young, highly star-forming dwarf galaxies and the majority belongs to the class of 'extreme emission line galaxies'. ...
ALMA Observations Show Major Mergers among the Host Galaxies of Fast-growing, High-redshift, Supermassive Black Holes
(IOP Publishing, 2017)
We present new ALMA band-7 data for a sample of six luminous quasars at z similar or equal to 4.8, powered by fast-growing supermassive black holes (SMBHs) with rather uniform properties: the typical accretion rates and ...
The galaxy size – halo mass scaling relations and clustering properties of central and satellite galaxies
(Oxford University Press, 2021-08)
In this work, we combine size and stellar mass measurements from the Sloan Digital Sky Server (SDSS) with the group finder algorithm of Rodriguez & Merchán in order to determine the stellar and halo mass-size relations of ...
THE SWIFT GRB HOST GALAXY LEGACY SURVEY. II. REST-FRAME NEAR-IR LUMINOSITY DISTRIBUTION AND EVIDENCE FOR A NEAR-SOLAR METALLICITY THRESHOLD
(IOP PUBLISHING LTD, 2016)
We present rest-frame near-IR (NIR) luminosities and stellar masses for a large and uniformly selected population of gamma-ray burst (GRB) host galaxies using deep Spitzer Space Telescope imaging of 119 targets from the ...
