We present a detailed analysis of the extended structure detected around the young and close-by Herbig Ae/Be star RCrA. This is a young triple system with an intermediate mass cent…
A few StePS forward in unveiling the complexity of galaxy evolution: light-weighted stellar ages of intermediate redshift galaxies with WEAVE
L. Costantin, A. Iovino, S. Zibetti +29
The upcoming new generation of optical spectrographs on four-meter-class telescopes will provide invaluable information for reconstructing the history of star formation in individu…
A Color-Excess Extinction map of the Southern Galactic disk from the VVV and GLIMPSE Surveys
M. Soto, R. Barbá, D. Minniti +24
An improved high-resolution and deep A foreground dust extinction map is presented for the Galactic disk area within , $-1.0^{\c…
The Tale of the Milky Way Globular Cluster NGC 6362 -- I. The Orbit and its possible extended star debris features as revealed by Gaia DR2
Richa Kundu, José G. Fernández-Trincado, Dante Minniti +5
We report the identification of possible extended star debris candidates beyond the cluster tidal radius of NGC 6362 based on the second {\it Gaia} data release ({\it Gaia} DR2). W…
The VIMOS Public Extragalactic Redshift Survey (VIPERS) -- Environment-size relation of massive passive galaxies at 0.5 < z < 0.8
A. Gargiulo, O. Cucciati, B. Garilli +36
We use the statistics of the VIPERS survey to investigate the relation between the surface mean stellar mass density Sigma=Mstar/(2*pi*Re^2) of massive passive galaxies (MPGs, Msta…
Reconstruction and exact solutions for cosmological perturbations from a generalized gravity theory
José Antonio Belinchón, Carlos González, Ramón Herrera
Scalar and tensor cosmological perturbations during an inflationary universe scenario in the context of the a generalized gravity theory are studied. This analyze is carried out co…
First resolved observations of a highly asymmetric debris disc around HD 160305 with VLT/SPHERE
Clément Perrot, Philippe Thebault, Anne-Marie Lagrange +36
Context. Direct imaging of debris discs gives important information about their nature, their global morphology, and allows us to identify specific structures possibly in connectio…
