Colour distributions in E-S0 galaxies. [PDF]

open access: yesAstronomy and Astrophysics Supplement Series, 2000
Colours distributions have been studied in 12 S0 galaxies, most of these nearly edge-on, from high resolution frames obtained at the CFHT and the Pic du Midi 2 m telescope, supplemented for some purposes by low resolution frames from the Observatoire de Haute Provence 120 cm telescope.

The star formation history of early-type galaxies in the fornax cluster [PDF]

open access: yes, 1998
We have measured central line strengths and line-strength gradients for a complete sample of early-type galaxies in the Fornax cluster, comprising 11 elliptical and 11 lenticular galaxies, more luminous than M(_B) = -17.

Line-strength indices and velocity dispersions for 148 early-type galaxies in different environments [PDF]

open access: yes, 2002
We have derived high quality line-strength indices and velocity dispersions for a sample of 148 early-type galaxies in different environments. The wavelength region covered by the observations ($\lambda \simeq 4600$ to 6600 Å) includes the Lick/IDS ...

H i Gas and Star Formation in Major Galaxy Pairs from the FAST All Sky H i Survey (FASHI)

open access: yesThe Astrophysical Journal
Atomic hydrogen (H i ) plays a fundamental role in fueling star formation in galaxies. However, the behavior of H i gas in interacting systems, particularly galaxy pairs, remains elusive.

Diverse reddening distributions in sight lines for type Ia supernovae

open access: yesAstronomy & Astrophysics
Context. Accurate cosmological constraints from type Ia supernovae (SNe) require sufficiently accurate corrections for host-galaxy extinction. Modelling these corrections is challenged by the problem of disentangling the SN’s intrinsic colours from host ...

Simulating molecular cloud regulated star formation in Galaxies [PDF]

open access: yes, 2007
This thesis is primarily concerned with understanding the process of galaxy formation via the simulation of the interstellar medium, star formation and supernova feedback.

The Delay Time Distribution of Tidal Disruption Events

open access: yesThe Astrophysical Journal
Tidal disruption events (TDEs) can be observed when stars get too close to supermassive black holes and are torn apart and accreted. The delay time distribution of TDEs, or rate of TDEs as a function of time since a burst of star formation, can be used ...

The clustering and X-ray properties of faint galaxies [PDF]

open access: yes, 1994
The clustering properties of faint (23 ≤ B ≤ 27) galaxies were investigated, with the aim of obtaining information about their redshift distribution, N(z), and therefore about the processes of galaxy evolution causing the steep rise in the galaxy number ...
