DWARF GALAXIES OF THE LOCAL GROUP [PDF]

, 1998
▪ Abstract The Local Group dwarf galaxies offer a unique window to the detailed properties of the most common type of galaxy in the Universe. In this review, I update the census of Local Group dwarfs based on the most recent distance and radial velocity ...

Counterrotation in Galaxies [PDF]

Symposium - International Astronomical Union, 1999
The phenomenon of counterrotation is observed when two galaxy components have their angular momenta projected antiparallel onto the sky. It follows that if the two components rotate around the same axis, the counter-rotation is intrinsic. On the contrary the counterrotation is only apparent if the rotation axes are misaligned and the line-of-sight lies

Structural and Morphological Properties of Ultraluminous Infrared Galaxies at 1 < z < 3

Open Astronomy, 2015
Using the Hubble Space Telescope (HST)/Wide Field Camera 3 (WFC3) near-infrared high-resolution imaging from the 3D-HST survey, we analyze the morphology and structure of 502 ultraluminous infrared galaxies (ULIRGs; LIR > 1012L⊙) at 1 < z < 3. Their rest-

Alignment of galaxies relative to their local environment in SDSS-DR8

, 2016
We study the alignment of galaxies relative to their local environment in SDSS-DR8 and, using these data, we discuss evolution scenarios for different types of galaxies. We defined a vector field of the direction of anisotropy of the local environment of

The triggering probability of radio-loud AGN: A comparison of high and low excitation radio galaxies in hosts of different colors [PDF]

, 2012
Low luminosity radio-loud active galactic nuclei (AGN) are generally found in massive red elliptical galaxies, where they are thought to be powered through gas accretion from their surrounding hot halos in a radiatively inefficient manner.

Theoretical Modeling of Starburst Galaxies [PDF]

, 2001
We have modeled a large sample of infrared starburst galaxies using both the PEGASE v2.0 and STARBURST99 codes to generate the spectral energy distribution (SED) of the young star clusters.

The luminosity function of field galaxies

, 2011
Schmidt's method for construction of luminosity function of galaxies is generalized by taking into account the dependence of density of galaxies from the distance in the near Universe.

Stellar masses and star formation histories for 105 galaxies from the Sloan Digital Sky Survey [PDF]

, 2002
We develop a new method to constrain the star formation histories, dust attenuation and stellar masses of galaxies. It is based on two stellar absorption-line indices, the 4000-A break strength and the Balmer absorption-line index Hδ A .

Galaxy Halo Masses from Galaxy‐Galaxy Lensing

The Astrophysical Journal, 2001
We present measurements of the extended dark halo profiles of bright early type galaxies at redshifts 0.1 to 0.9 obtained via galaxy-galaxy lensing analysis of images taken at the CFHT using the UH8K CCD mosaic camera. Six half degree fields were observed for a total of 2 hours each in I and V, resulting in catalogs containing ~20 000 galaxies per ...

KiDS+VIKING+GAMA: Testing semi-analytic models of galaxy evolution with galaxy–galaxy–galaxy lensing [PDF]

Astronomy & Astrophysics, 2020
Context. Several semi-analytic models (SAMs) try to explain how galaxies form, evolve, and interact inside the dark matter large-scale structure. These SAMs can be tested by comparing their predictions for galaxy–galaxy–galaxy lensing (G3L), which is weak gravitational lensing around galaxy pairs, with observations. Aims.
