Non-linearity and environmental dependence of the star forming galaxies Main Sequence
G. Erfanianfar, P. Popesso, A. Finoguenov +30
Using data from four deep fields (COSMOS, AEGIS, ECDFS, and CDFN), we study the correlation between the position of galaxies in the star formation rate (SFR) versus stellar mass pl…
Primordial Black Holes as Near Infrared Background sources
D. Manzoni, F. Ziparo, S. Gallerani +1
The near infrared background (NIRB) is the collective light from unresolved sources observed in the band 1-10 m. The measured NIRB angular power spectrum on angular scales $θ\…
LoCuSS: Testing hydrostatic equilibrium in galaxy clusters
G. P. Smith, P. Mazzotta, N. Okabe +17
We test the assumption of hydrostatic equilibrium in an X-ray luminosity selected sample of 50 galaxy clusters at from the Local Cluster Substructure Survey (LoCuSS).…
The XXL Survey. II. The bright cluster sample: catalogue and luminosity function
F. Pacaud, N. Clerc, P. A. Giles +40
Context. The XXL Survey is the largest survey carried out by the XMM-Newton satellite and covers a total area of 50 square degrees distributed over two fields. It primarily aims at…
Ultra-deep catalog of X-ray groups in the Extended Chandra Deep Field South
A. Finoguenov, M. Tanaka, M. Cooper +22
Ultra-deep observations of ECDF-S with Chandra and XMM-Newton enable a search for extended X-ray emission down to an unprecedented flux of ergs s cm…
The evolution of star formation activity in galaxy groups
G. Erfanianfar, P. Popesso, A. Finoguenov +30
We study the evolution of the total star formation (SF) activity, total stellar mass and halo occupation distribution in massive halos by using one of the largest X-ray selected sa…
The XXL Survey. XIII. Baryon content of the bright cluster sample
D. Eckert, S. Ettori, J. Coupon +20
Traditionally, galaxy clusters have been expected to retain all the material accreted since their formation epoch. For this reason, their matter content should be representative of…
LoCuSS: The slow quenching of star formation in cluster galaxies and the need for pre-processing
C. P. Haines, M. J. Pereira, G. P. Smith +8
We present a study of the spatial distribution and kinematics of star-forming galaxies in 30 massive clusters at 0.15<z<0.30, combining wide-field Spitzer 24um and GALEX NUV imagin…
The XXL Survey: I. Scientific motivations - XMM-Newton observing plan - Follow-up observations and simulation programme
M. Pierre, F. Pacaud, C. Adami +89
We present the XXL Survey, the largest XMM programme totaling some 6.9 Ms to date and involving an international consortium of roughly 100 members. The XXL Survey covers two extrag…
Reversal or no reversal: the evolution of the star formation rate-density relation up to z~1.6
F. Ziparo, P. Popesso, A. Finoguenov +27
We investigate the evolution of the star formation rate (SFR)-density relation in the Extended Chandra Deep Field South (ECDFS) and the Great Observatories Origin Deep Survey (GOOD…
In the whirlpool's coils: tracing substructure from combined optical/X-ray data in the galaxy cluster A1300
F. Ziparo, F. G. Braglia, D. Pierini +3
Structure formation is thought to act via hierarchical mergers and accretion of smaller systems driven by gravity with dark matter dominating the gravitational field. Combining X-r…
First simultaneous optical/near-infrared imaging of an X-ray selected, high-redshift cluster of galaxies with GROND: the galaxy population of XMMU J0338.7+0030 at z=1.1
D. Pierini, R. Suhada, R. Fassbender +28
The XMM-Newton Distant Cluster Project is a serendipitous survey for clusters of galaxies at redshifts z>=0.8 based on deep archival XMM-Newton observations. ... Low-significance c…
The XXL Survey X: K-band luminosity - weak-lensing mass relation for groups and clusters of galaxies
F. Ziparo, G. P. Smith, S. L. Mulroy +15
We present the K-band luminosity-halo mass relation, , for a subsample of 20 of the 100 brightest clusters in the XXL Survey observed with WIRCam at the Canad…
The evolution of galaxy star formation activity in massive halos
P. Popesso, A. Biviano, A. Finoguenov +20
There is now a large consensus that the current epoch of the Cosmic Star Formation History (CSFH) is dominated by low mass galaxies while the most active phase at 1<z<2 is dominate…
Interpreting ALMA non-detections of JWST super-early galaxies
M. Kohandel, A. Ferrara, A. Pallottini +3
Recent attempts to detect [OIII] 88m emission from super-early () galaxy candidates observed by JWST have been unsuccessful. By using zoom-in simulations, we show that th…

The role of massive halos in the Star Formation History of the Universe
P. Popesso, A. Biviano, A. Finoguenov +21
The most striking feature of the Cosmic Star Formation History (CSFH) of the Universe is a dramatic drop of the star formation (SF) activity, since z~1. In this work we investigate…
