SAURON: Observations of E/S0/Sa galaxies

open access: yes, 2002
We present results from a new and unique integral-field spectrograph, SAURON. It has a large field of view and high throughput and is primarily built for the study of stellar & gaseous kinematics and stellar populations in galaxies. Its aim is to carry out a systematic survey of the velocity fields, velocity dispersions, and line-strength ...

Colour distributions in E-S0 galaxies [PDF]

open access: yesAstronomy and Astrophysics Supplement Series, 1999
The colours distributions (with R in Cousins's system) have been measured in 44 E classified galaxies in the Local Supercluster, from pairs of frames collected by Nieto and co-workers in 1989-91. These are nearly all from the CFHT, and of sub-arsec resolution.

The properties of discrete X-ray sources in star-forming galaxies [PDF]

open access: yes, 2012
Observations of starburst galaxies have revealed a large number of point-like X-ray sources located within these systems, including active galactic nuclei (AGN), X-ray binaries (XRBs), and utraluminous X-ray sources (ULXs).

The Hα Concentration of Local Star-forming Galaxies: Implications for Galaxy Structure Formation

open access: yesThe Astrophysical Journal
In this work, we present a study on the H α emission line flux concentration of 3098 low-redshift star-forming galaxies (SFGs) using the MaNGA data available in the Data Release 17 from the Sloan Digital Sky Survey (SDSS).

Molecular hydrogen in galaxies [PDF]

open access: yes, 1987
This study aims to understand the key role played by molecular hydrogen in the evolution of galaxies, with a view to constraining its radial distribution in the Galaxy and the CO→H(_2) conversion factor α(_20).The star formation rate is shown to be ...

Morphological Demographics of Galaxies at z ∼ 10–16: Log-normal Size Distribution and Exponential Profiles Consistent with the Disk Formation Scenario

open access: yesThe Astrophysical Journal
We homogeneously investigate the morphological properties of 169 galaxies at z  ∼ 10–16 with deep JWST NIRCam images employing our established techniques of GALFIT modeling and uncertainty evaluation (systematics+statistics).

Groups, clusters and superclusters of galaxies [PDF]

open access: yes, 1991
Galaxies are observed in a diverse range of associations. Understanding the dynamical, statistical and clustering properties of aggregations of galaxies forms the main body of this thesis.

Chemical and kinematical evolution in nearby dwarf spheroidal galaxies [PDF]

open access: yes, 2006
Dwarf spheroidal (dSph) galaxies are the least massive and luminous objects known to exist. These galaxies are often considered as the fossil building blocks of massive systems predicted by some cosmological models.

The effect of the environment on the evolution of galaxy colours [PDF]

open access: yes, 2006
In chapter 1 of this thesis, I give a brief overview of the birth of modern cosmology and the growth of the current paradigm. I then go on to describe the different types of galaxies, the star formation rates within them and give some notes about galaxy ...
