The first galaxies in the Hubble Frontier Fields
Published 2019“…To obtain these results, we have developed a novel method to subtract the massive foreground galaxies that lie close to the critical line from the MACSJ0416.1-2403 cluster, allowing for a deeper and cleaner detection of the faintest systems at $z\geq6$. …”

The impact of the FREDDA dedispersion algorithm on H0 estimations with fast radio bursts
Published 2024“…Recently, FRBs were used to make an independent measure of the Hubble constant H0, promising to resolve the Hubble tension given a sufficient number of detected FRBs. …”

Starburst and old population in z=3.8 radio galaxies with Pégase.3
Published 2012“…Distant radio galaxies, hosted by massive ellipticals, follow the galaxy evolution process on an extremely large (0 = z =7) time-scale = 10 12Gyrs, up to primeval galaxies. …”

Multiband counterparts of two eclipsing ultraluminous X-ray sources in M51
Published 2018“…We present the discovery and interpretation of ionized nebulae around two ultraluminous X-ray sources in M 51; both sources share the rare property of showing X-ray eclipses by their companion stars and are therefore prime targets for follow-up studies. Using archival Hubble Space Telescope images, we found an elongated, 100-pc-long emission-line structure associated with one X-ray source (CXOM51 J132940.0+471237; ULX-1 for simplicity), and a more circular, ionized nebula at the location of the second source (CXOM51 J132939.5+471244; ULX-2 for simplicity). …”

Dark energy: EFTs and supergravity
Published 2022“…As it rolls, a tower of heavy states will generically descend, triggering a phase transition in the low energy cosmological dynamics after at most a few hundred Hubble times. As a result, dark energy domination cannot continue indefinitely and there is at least a percentage chance that we find ourselves in the first Hubble epoch. …”

A CO-rich merger shaping a powerful and hyperluminous infrared radio galaxy at z = 2: The Dragonfly Galaxy
Published 2015“…Most of this widespread CO(1–0) appears to follow prominent tidal features visible in the rest-frame near-UV HST/WFPC2 imaging. …”

Ultra-bright Optical Transients are Linked with Type Ic Supernovae
Published 2010“…The initial discoveries of SN 2005ap by the Texas Supernova Search and SCP-06F6 in a deep Hubble pencil beam survey were followed by the Palomar Transient Factory confirmation of host redshifts for other similar transients. …”

An e-VLBI image of SN1987A from Australian radio telescopes and the JIVE correlator
Published 2009“…The e-VLBI data at 1.4 GHz show good agreement with the ATCA data at 9GHz, resolving the substructure in the equatorial brightness enhancements of the remnant(allowing for the fact that the e-VLBI observations are sensitive to structure on angular scales<0.4?). …”

Herschel-ATLAS: modelling the first strong gravitational lenses
Published 2014“…We present an enhancement of the semilinear lens inversion method of Warren & Dye which allows simultaneous reconstruction of several different wavebands and apply this to dual-band imaging of the lenses acquired with the Hubble Space Telescope. …”

Amuse-field. II. Nucleation of early-type galaxies in the field versus cluster environment
Published 2014“…The optical light profiles of nearby early-type galaxies are known to exhibit a smooth transition from nuclear light deficits to nuclear light excesses with decreasing galaxy mass, with as much as 80% of the galaxies with stellar masses below 1010 M ? hosting a massive nuclear star cluster (NSC). …”

Outbursts of the intermediate-mass black hole HLX-1: a wind-instability scenario
Published 2017“…We model the intermediate-mass black hole HLX-1, using the Hubble Space Telescope, XMM–Newton and Swift. We quantify the relative contributions of a bluer component, function of X-ray irradiation, and a redder component, constant and likely coming from an old stellar population. …”

Linking the structural properties of galaxies and their star formation histories with STAGES
Published 2016“…The galaxies inhabit a very broad range of environments, from cluster cores to the field. Using Hubble Space Telescope (HST) images, we quantify their structure following Hoyos et al., and divide them into disturbed and undisturbed. …”
