The evolution of late-type galaxies from CASSOWARY lensing systems [PDF]

, 2014
We explore the properties of lensing galaxies and lensed faint sources at redshifts between 1.5 and 3.0. Our sample consists of 9 carefully selected strongly-lensed galaxies discovered by the CASSOWARY survey in the Sloan Digital Sky Survey (SDSS) data ...

A catalog of extended clusters and ultra-compact dwarf galaxies - An analysis of their parameters in early- and late-type galaxies [PDF]

, 2012
Extended stellar clusters with effective radii larger than 10 pc have been found in various environments. Objects with masses comparable to globular clusters (GCs) are called extended clusters (ECs), while objects with masses in the dwarf galaxy regime ...

A Morphological-type dependence in the mu_0-log(h) plane of Spiral galaxy disks [PDF]

, 2001
We present observational evidence for a galaxy `Type' dependence to the location of a spiral galaxy's disk parameters in the mu_0-log(h) (central disk surface-brightness - disk scale-length) plane.

Far-infrared colours of nearby late-type galaxies in the Herschel Reference Survey [PDF]

, 2012
We study the far infrared (60–500 μm) colours of late-type galaxies in the Herschel Reference Survey, a K-band selected, volume limited sample of nearby galaxies.

Understanding the Fundamental Plane and the Tully Fisher Relation

Frontiers in Astronomy and Space Sciences, 2020
The relation between early type galaxy size, surface brightness and velocity dispersion, “the fundamental plane,” has long been understood as resulting from equilibrium in their largely pressure supported stellar dynamics.

Galaxy Dynamics from Edge-On Late-type Galaxies

, 1999
We present first results of a program to study the dynamics of undisturbed bulgeless, low surface density disk galaxies in order to probe the underlying structure of dark matter halos. High resolution H-alpha rotation curves are combined with optical and infrared imaging to place strong limits on the halo profiles.

The VIMOS VLT Deep Survey - Evolution of the luminosity functions by galaxy type up to z=1.5 from first epoch data [PDF]

, 2006
From the first epoch observations of the VVDS up to z=1.5 we have derived luminosity functions (LF) of different spectral type galaxies. The VVDS data, covering ~70% of the life of the Universe, allow for the first time to study from the same sample and ...

On the dust abundance gradients in late-type galaxies – I. Effects of destruction and growth of dust in the interstellar medium [PDF]

, 2012
We present basic theoretical constraints on the effects of destruction by supernovae (SNe) and growth of dust grains in the interstellar medium (ISM) on the radial distribution of dust in late-type galaxies.

Morphological Dependence of Star Formation Properties for the Galaxies in the Merging Galaxy Cluster A2255

, 2005
The merging cluster of galaxies A2255 is covered by the Sloan Digital Sky Survey (SDSS) survey. In this paper we perform a morphological classification on the basis of the SDSS imaging and spectral data, and investigate the morphological dependence of ...
