Photometric and kinematical study of nearby groups of galaxies around IC 65 and NGC 6962 [PDF]
, 2006 We discuss the structure, galaxy content and kinematics of a sparse, probably collapsing group around IC 65 and an evolved rich group around NGC 6962Comment: Poster contribution on 2 pages with 2 figures to be published in ESO Astrophysics Symposia ...

Astrophysical tests of modified gravity: the morphology and kinematics of dwarf galaxies [PDF]
Journal of Cosmology and Astroparticle Physics, 2013 This paper is the third in a series on tests of gravity using observations of stars and nearby dwarf galaxies. We carry out four distinct tests using published data on the kinematics and morphology of dwarf galaxies, motivated by the theoretical work of Hui et al. (2009) and Jain and Vanderplas (2011). In a wide class of gravity theories a scalar field

Observed Properties of Dark Matter on Small Spatial Scales [PDF]
, 2007 The nature of dark matter is one of the outstanding questions of astrophysics. The internal motions of member stars reveal that the lowest luminosity galaxies in the Local Group are the most dark-matter dominated.

The black hole mass of BL Lacs from stellar velocity dispersion of the host galaxy [PDF]
, 2001 We present the first results from our on-going program to estimate black hole masses [M(BH)] of nearby BL Lac objects. The estimates are based on stellar velocity dispersion (sigma) of the BL Lac host galaxies from optical spectroscopy, and the recently ...

Optical surface photometry of radio galaxies - II. Observations and data analysis [PDF]
, 1999 Optical imaging observations for 50 radio galaxies are presented. For each object isophotal contours, photometric profiles, structural parameters (position angle, ellipticity, Fourier coefficients), and total magnitudes are given.

The Symmetry, Color and Morphology of Galaxies in the Hubble Deep Field [PDF]
, 1998 We present a new method of utilizing the color and asymmetry values for galaxies in the Hubble Deep Field to determine both their morphological features and physical parameters.

Astrophysical Statistics of 745 Compact Galaxies Near the Galactic North Pole [PDF]
Symposium - International Astronomical Union, 1972 A brief description is given of methods used to find 745 compact galaxies in a 36 sq deg-field around M3. These constitute 24–40% of all galaxies in this area, brighter than 18.5 magnitude in B. Significant clustering found is related to Zwicky clusters of compact galaxies. Photographic 3-color photometry has been carried out.

Astronomische Nachrichten, EarlyView.ABSTRACT Planetary nebulae represent a late evolutionary phase of low‐ to intermediate‐mass stars. In this article, we present the serendipitous discovery of a previously unknown, faint potential Galactic planetary nebula (PN) in the constellation Camelopardalis, identified during a survey‐inspection, aiming at the detection of dwarf companions of the ...
