Evolution and role of mergers in the BCG-cluster alignment. A view from cosmological hydrosimulations
(Wiley Blackwell Publishing, Inc, 2020-06)
Contradictory results have been reported on the time evolution of the alignment between clusters and their brightest cluster galaxy (BCG).We study this topic by analysing cosmological hydrosimulations of 24 massive clusters ...
Baryons Shaping Dark Matter Haloes
(Wiley Blackwell Publishing, Inc, 2020-12)
In this work we aim at investigating the effects of baryons on the dark matter (DM) haloes structure, focusing on the correlation between the presence and importance of stellar discs and the halo shapes. We study the ...
Non-thermal emission resulting from a supernova explosion inside an extragalactic jet
(EDP Sciences, 2019-02)
Context. Core-collapse supernovae are found in galaxies with ongoing star-formation. In a starburst galaxy hosting an active galactic nucleus with a relativistic jet, supernovae can take place inside the jet. The collision ...
The better half - asymmetric star formation due to ram pressure in the EAGLE simulations
(Wiley Blackwell Publishing, Inc, 2020-10)
We use the EAGLE simulations to study the effects of the intracluster medium on the spatially resolved star formation activity in galaxies. We study three cases of galaxy asymmetry dividing each galaxy into two halves using ...
Semi-analytic galaxies-I. synthesis of environmental and star-forming regulation mechanisms
(Wiley Blackwell Publishing, Inc, 2018-09)
We present results from the semi-analytic model of galaxy formation SAG applied on the MULTIDARK simulation MDPL2. SAG features an updated supernova (SN) feedback scheme and a robust modelling of the environmental effects ...
Semi-analytic galaxies: I. Synthesis of environmental and star-forming regulation mechanisms
(Wiley Blackwell Publishing, Inc, 2018-09)
We present results from the semi-analytic model of galaxy formation SAG applied on the MULTIDARK simulation MDPL2. SAG features an updated supernova (SN) feedback scheme and a robust modelling of the environmental effects ...
Host galaxy properties and environment of obscured and unobscured X-ray selected active galactic nuclei in the COSMOS survey
(Wiley Blackwell Publishing, Inc, 2020-03)
We analyse different photometric and spectroscopic properties of active galactic nuclei (AGNs) and quasars (QSOs) selected by their mid-IR power-law and X-ray emission from the COSMOS survey. We use a set of star-forming ...
Semi-analytic galaxies. III: the impact of supernova feedback on the mass-metallicity relation
(Wiley Blackwell Publishing, Inc, 2018-11)
We use the semi-analytic model (SAM) of galaxy formation and evolution SAG coupled with the MULTIDARK simulation MDPL2 to study the evolution of the stellar - gas metallicity relation of galaxies (MZR). We test several ...
Asymmetric star formation efficiency due to ram pressure stripping
(MDPI AG, 2016-12)
Previous works have shown that a dense cluster environment affects satellite galaxy properties and accelerates or truncates their evolutionary processes. In this work, we use the EAGLE simulation to study this effect, ...
Overdensity of VVV galaxies behind the Galactic bulge
(EDP Sciences, 2021-02)
Context. The extragalactic vision we have through the Milky Way is very unclear. There is significant extinction of the optical emission from objects located in the region called the zone of avoidance (ZOA). NIR wavelengths ...
