A new analytic ram pressure profile for satellite galaxies
(Wiley Blackwell Publishing, Inc, 2021-10)
We present a new analytic fitting profile to model the ram pressure exerted over satellite galaxies on different environments and epochs. The profile is built using the information of the gas particle distribution in ...
Assembly of spheroid-dominated galaxies in the EAGLE simulation
(EDP Sciences, 2019-08)
Context. Despite the insights gained in the last few years, our knowledge about the formation and evolution scenario for the spheroid-dominated galaxies is still incomplete. New and more powerful cosmological simulations ...
Green Peas in X-Rays
(IOP Publishing, 2019-08)
Green Peas represent a population of compact, highly star-forming dwarf galaxies at redshifts z ∼ 0.2-0.3 that have recently been found to show signatures of ultraviolet ionizing radiation leakage. They are being considered ...
The Far-infrared Emission of the First Massive Galaxies
(IOP Publishing, 2018-10)
Massive Population II galaxies undergoing the first phase of vigorous star formation after the initial Population III stage should have high energy densities and silicate-rich interstellar dust. We have modeled the resulting ...
Compact groups from semi-analytical models of galaxy formation-II. Different assembly channels
(Wiley Blackwell Publishing, Inc, 2021-05)
We study the formation of over 6000 compact groups (CGs) of galaxies identified in mock redshift-space galaxy catalogues built from semi-analytical models of galaxy formation (SAMs) run on the Millennium Simulations. We ...
The manifestation of secondary bias on the galaxy population from IllustrisTNG300
(Wiley Blackwell Publishing, Inc, 2020-06)
We use the improved IllustrisTNG300 magnetohydrodynamical cosmological simulation to revisit the effect that secondary halo bias has on the clustering of the central galaxy population. With a side length of 205 h−1 Mpc and ...
The impact of bars and interactions on optically selected AGNs in spiral galaxies
(EDP Sciences, 2018-10)
Aims. With the aim of performing a suitable comparison of the internal process of galactic bars with respect to the external effect of interactions on driving gas toward the inner most region of the galaxies, we explored ...
Nature and chemical abundances of a sample of Lyman-α emitter objects at high redshift
(Wiley Blackwell Publishing, Inc, 2018-09)
We built a grid of photoionization models and compiled already available observational emission line intensities (1000 < λ(Å) < 2000) of confirmed star formation regions and Active Galactic Nucleus (AGNs) in order to ...
Velocity dispersion of brightest cluster galaxies in cosmological simulations
(Wiley Blackwell Publishing, Inc, 2021-11)
Using the DIANOGA hydrodynamical zoom-in simulation set of galaxy clusters, we analyse the dynamics traced by stars belonging to the brightest cluster galaxies (BCGs) and their surrounding diffuse component, forming the ...
BCG mass evolution in cosmological hydro-simulations
(Wiley Blackwell Publishing, Inc, 2018-09)
We analyze the stellar growth of brightest cluster galaxies (BCGs) produced by cosmological zoom-in hydrodynamical simulations of the formation of massive galaxy clusters. The evolution of the stellar mass content is studied ...
