Direct Lyman continuum and Lyman-alpha escape observed at redshift 4
E. Vanzella, M. Nonino, G. Cupani +16
We report on the serendipitous discovery of a z=4.0, M1500=-22.20 star-forming galaxy (Ion3) showing copious Lyman continuum (LyC) leakage (~60% escaping), a remarkable multiple pe…
Mass profile decomposition of the Frontier Fields cluster MACS J0416-02403. Insights on the Dark-Matter inner profile
M. Annunziatella, M. Bonamigo, C. Grillo +8
We present a high resolution dissection of the two-dimensional total mass distribution in the core of the Hubble Frontier Fields galaxy cluster MACS J0416.1-2403, at z ~ 0.396. We…
Weak-lensing calibration of a stellar mass-based mass proxy for redMaPPer and Voronoi Tessellation clusters in SDSS Stripe 82
Maria E. S. Pereira, Marcelle Soares-Santos, Martin Makler +9
We present the first weak lensing calibration of , a new galaxy cluster mass proxy corresponding to the total stellar mass of red and blue members, in two cluster sample…
Two Peculiar Fast Transients in a Strongly Lensed Host Galaxy
S. A. Rodney, I. Balestra, M. Bradac +32
A massive galaxy cluster can serve as a magnifying glass for distant stellar populations, with strong gravitational lensing exposing details in the lensed background galaxies that…
Mass distribution in the core of MACS J1206: robust modeling from an exceptionally large sample of central multiple images
G. B. Caminha, C. Grillo, P. Rosati +24
We present a new strong lensing analysis of the galaxy cluster MACS J1206.2-0847 (MACS 1206), at z=0.44, using deep spectroscopy from CLASH-VLT and VLT/MUSE archival data in combin…
MACS J0416.1-2403: Impact of line-of-sight structures on strong gravitational lensing modelling of galaxy clusters
G. Chirivì, S. H. Suyu, C. Grillo +5
Exploiting the powerful tool of strong gravitational lensing by galaxy clusters to study the highest-redshift Universe and cluster mass distributions relies on precise lens mass mo…
VICS82: the VISTA-CFHT Stripe 82 near-infrared survey
J. E. Geach, Y-T. Lin, M. Makler +14
We present the VISTA-CFHT Stripe 82 (VICS82) survey: a near-infrared (J+Ks) survey covering 150 square degrees of the Sloan Digital Sky Survey (SDSS) equatorial Stripe 82 to an ave…
Joining X-ray to lensing: an accurate combined analysis of MACS J0416.12403
M. Bonamigo, C. Grillo, S. Ettori +6
We present a novel approach for a combined analysis of X-ray and gravitational lensing data and apply this technique to the merging galaxy cluster MACS J0416.12403. The method e…
CLASH-VLT: constraints on gravity models with galaxy clusters using lensing and kinematic analyses
L. Pizzuti, B. Sartoris, L. Amendola +10
We perform a maximum likelihood kinematic analysis of the two dynamically relaxed galaxy clusters MACS J1206.2-0847 at and RXC J2248.7-4431 at to determine the to…
Magnifying the early episodes of star formation: super star clusters at cosmological distances
E. Vanzella, M. Castellano, M. Meneghetti +27
We study the spectrophotometric properties of a highly magnified (μ~40-70) pair of stellar systems identified at z=3.2222 behind the Hubble Frontier Field galaxy cluster MACS~J0416…
The abundance of compact quiescent galaxies since z ~ 0.6
Aldée Charbonnier, Marc Huertas-Company, Thiago S. Gonçalves +12
We set out to quantify the number density of quiescent massive compact galaxies at intermediate redshifts. We determine structural parameters based on i-band imaging using the CFHT…
