The effect of galaxy mass ratio on merger-driven starbursts

TJ Cox, P Jonsson, RS Somerville… - Monthly Notices of …, 2008 - academic.oup.com
We employ numerical simulations of galaxy mergers to explore the effect of galaxy mass
ratio on merger-driven starbursts. Our numerical simulations include radiative cooling of gas …

The structure of classical bulges and pseudobulges: The link between pseudobulges and Sérsic index

DB Fisher, N Drory - The Astronomical Journal, 2008 - iopscience.iop.org
In this paper, we study the properties of pseudobulges (bulges that appear similar to disk
galaxies) and classical bulges (bulges which appear similar to E-type galaxies) in bulge …

The population of barred galaxies in the local universe-I. Detection and characterisation of bars

JAL Aguerri, J Méndez-Abreu, EM Corsini - Astronomy & Astrophysics, 2009 - aanda.org
Context. Bars are very common in the centre of the disc galaxies, and they drive the
evolution of their structure. The state-of-the-art imaging and redshift surveys of galaxies …

A catalog of visual-like morphologies in the 5 candels fields using deep learning

R Gravet, G Cabrera-Vives… - The Astrophysical …, 2015 - iopscience.iop.org
We present a catalog of visual-like H-band morphologies of∼ 50.000 galaxies (H f160w<
24.5) in the 5 CANDELS fields (GOODS-N, GOODS-S, UDS, EGS, and COSMOS) …

Bulge n and B/T in high-mass galaxies: constraints on the origin of bulges in hierarchical models

T Weinzirl, S Jogee, S Khochfar, A Burkert… - The Astrophysical …, 2009 - iopscience.iop.org
We use the bulge Sérsic index n and bulge-to-total mass ratio (B/T) to explore the
fundamental question of how bulges form. We perform two-dimensional bulge–disk–bar …

Photometric scaling relations of lenticular and spiral galaxies

E Laurikainen, H Salo, R Buta… - Monthly Notices of …, 2010 - academic.oup.com
Photometric scaling relations are studied for S0 galaxies and compared with those obtained
for spirals. New two-dimensional multi-component decompositions are presented for 122 …

Bulges of nearby galaxies with Spitzer: scaling relations in pseudobulges and classical bulges

DB Fisher, N Drory - The Astrophysical Journal, 2010 - iopscience.iop.org
We investigate scaling relations of bulges using bulge–disk decompositions at 3.6 μm and
present bulge classifications for 173 E-Sd galaxies within 20 Mpc. Pseudobulges and …

Structural properties of disk galaxies-I. The intrinsic equatorial ellipticity of bulges

J Méndez-Abreu, JAL Aguerri, EM Corsini… - Astronomy & …, 2008 - aanda.org
Context. A variety of formation scenarios have been proposed to explain the diversity of
properties observed in bulges. Studying their intrinsic shape can help to constrain the …

The X-shooter GRB afterglow legacy sample (XS-GRB)

J Selsing, D Malesani, P Goldoni, JPU Fynbo… - Astronomy & …, 2019 - aanda.org
In this work we present spectra of all γ-ray burst (GRB) afterglows that have been promptly
observed with the X-shooter spectrograph until 31/03/2017. In total, we have obtained …

Secular-and merger-built bulges in barred galaxies

J Méndez-Abreu, VP Debattista, EM Corsini… - Astronomy & …, 2014 - aanda.org
Context. Historically, galaxy bulges were thought to be single-component objects at the
center of galaxies. However, this picture is now questioned since different bulge types with …
