The circumnuclear environment of the peculiar galaxy NGC 3310 [PDF]

open access: yes, 2009
Gas and star velocity dispersions have been derived for eight circumnuclear star-forming regions (CNSFRs) and the nucleus of the spiral galaxy NGC3310 using high resolution spectroscopy in the blue and far red.

Galaxy Distances in the Nearby Universe: Corrections For Peculiar Motions [PDF]

open access: bronze, 1998
By correcting the redshift--dependent distances for peculiar motions through a number of peculiar velocity field models, we recover the true distances of a wide, all-sky sample of nearby galaxies (~ 6400 galaxies with velocities ...

J-PLUS: Tomographic analysis of galaxy angular density and redshift fluctuations in Data Release 3. Constraints on photo-$z$ errors, linear bias, and peculiar velocities

open access: diamondThe Open Journal of Astrophysics
The Javalambre Photometric Local Universe Survey (J-PLUS) is a spectro-photometricsurvey covering about 3,000~deg$^2$ in its third data release (DR3), and containing about 300,000 galaxies with high quality ({\it odds}$>0.8$) photometric redshifts ...

Measuring the Hubble Constant through the Galaxy Pairwise Peculiar Velocity

open access: goldThe Astrophysical Journal Letters
The Hubble constant H _0 , the current expansion rate of the Universe, is one of the most important parameters in cosmology. The cosmic expansion regulates the mutually approaching motion of a pair of celestial objects due to their gravity.

Structure and kinematics of the peculiar galaxy NGC 128 [PDF]

open access: yes, 1998
This is a multiband photometric and spectroscopic study of the peculiar S0 galaxy NGC128. We present results from broad (B and R) and narrow band optical CCD photometry, near (NIR) and far (FIR) infrared observations, long slit spectroscopy, and Fabry ...

Relative velocity of dark matter and barions in clusters of galaxies and measurements of their peculiar velocities [PDF]

open access: bronze, 2012
The increasing sensitivity of current experiments, which nowadays routinely measure the thermal SZ effect within galaxy clusters, provide the hope that peculiar velocities of individual clusters of galaxies will be measured rather soon using the ...

Photometric structure of the peculiar galaxy ESO 235-G58 [PDF]

open access: yes, 2004
We present the near-infrared and optical properties of the peculiar galaxy ESO 235-G58, which resembles a late-type ringed barred spiral seen close to face-on.

IGR J14488-4008: an X-ray peculiar giant radio galaxy discovered by INTEGRAL [PDF]

open access: yes, 2015
In this paper we report the discovery and detailed radio/X-ray analysis of a peculiar giant radio galaxy (GRG) detected by INTEGRAL, IGR J14488-4008. The source has been recently classified as a Seyfert 1.2 galaxy at redshift 0.123; the radio data denote

Minimization of biases in galaxy peculiar velocity catalogues [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2015
Galaxy distances and derived radial peculiar velocity catalogs constitute valuable datasets to study the dynamics of the Local Universe. However, such catalogs suffer from biases whose effects increase with the distance. Malmquist biases and lognormal error distribution affect the catalogs. Velocity fields of the Local Universe reconstructed with these
