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. ...

Well-resolved infrared observations of nearby galaxies are of fundamental importance to the study of the processes that affect galactic evolution. In this paper we report on the first imaging results from the Spitzer Infrared Nearby Galaxies Survey (SINGS) using observations of the Sb galaxy NGC 7331. ... As an example of the types of information that the full SINGS will provide, we use three methods to determine that the interstellar medium mass in the ring of NGC 7331 is ~5Г-109 Msolar. ...

... A radio galaxy is a galaxy that emits an unusually big amount of energy at radio wavelengths. ... Inside of each galaxy with an active nucleus (radio galaxies are among them) there must be a system of a "central machine" responsible for the colossal amount of the emitted energy from radio to gamma ranges. ... Sometimes a radio source in an active galaxy may flare again if the needed conditions appear (a new portion of matter would fall into the furnace of the "central machine"). ...

. Dwarf galaxies are amongst the most dark matter dominated stellar systems in the universe. Our observations of this however, are based on kinematic measurements that assume dynamic equilibrium. In this talk I will present the results of my first paper; a detailed analysis of the stellar substructure surrounding the Hercules dwarf spheroidal galaxy, demonstrating that Hercules is a strongly tidally disrupted system and therefore not in dynamic equilibrium.

... By comparison, old elliptical galaxies have a wide range of Lx(gas) and some of them (e.g., group or cluster dominant galaxies) have Lx(gas) 10 or 100 times higher than Lx(LMXB). One of the key observables to address the age effect is the abundance ratio of Fe to elements, b ecause of different pro duction yields of SNe Ia and I I. In the merger scenario of young elliptical galaxies, we would exp ect an enrichment of -elements from SN I I, asso ciated with the recent star formation. ...
