We select in the database all galaxies with known velocity and magnitude and similar to a given template for which we know the distance, the magnitude and the radial velocity. ... We simply have to choose a property which does not depend on the distance, as for example the rotation velocity ( log(vrot) ) and select the galaxies having log(vrot) in a very narrow range around the value for the template galaxy. ... leda@univ-lyon1.fr ...

K-band Arcetri Obscured Supernova Search . What is the KAOSS Project? W hat is the KAOSS Project? Some recent surveys aimed at detecting Supernovae (SNe) in the optical have found that starburst galaxies do not show evidence for an enhanced SN rate, with respect to quiescent galaxies (Richmond et al. ... A similar result was obtained by Navasardyan et al. (2001) who looked for SNe in interacting galaxies, finding no evidence for correlations between SN rate and galaxy properties. ...

Galaxies follow tight scaling relations linking their dynamical properties to their baryonic content. The study of these dynamical laws strongly constrains cosmological models of galaxy formation. I will present new results on the baryonic Tully-Fisher relation (BTFR), which links the total baryonic mass of a galaxy to its outer rotation velocity. I will discuss both successes and failures of LCDM models that attempt to reproduce the BTFR using gas outflows from stellar feedback. ...

A comparative study of type I and type II supernovae . ... Sternberg State Astronomical Institute, Moscow, U.S.S.R. (Received 26 November, 1985) . ... No significant difference between SNe I and SNe II has been found in their radial distribution and frequency of outbursts in spiral galaxies. ... The radial distribution of type Ia SNe in spiral galaxies is only slightly steeper than the one for SNe II, while SNe Ib/c are more concentrated towards the central regions. ...

Do LIRGs follow the Tully-Fisher relation? ... For a small we can say majority of investigate i Conclusion number of galaxies in our sample, that the T-F relation holds. ... The purpose of this research was to study the LIRGs (Luminous Infrared Galaxies) and see if they follow the Tully-Fisher relation. The LIRGs are different to normal galaxies in the fact that they emit 90% of their light in infrared. ... The faster the galaxy rotates, the wider is the emission line in velocity. ...
