The rotation curves of a sample of 46 low- and high-surface brightness galaxies are considered in the context of Milgrom's modi_ed dynamics (MOND) to test a new interpolating function proposed by Zhao et al. (2010) [1] and compare with the results of simple interpolating function. The predicted rotation curves are calculated from the total baryonic matter based on the B-band surface photometry,...

We decompose the COBE/DIRBE observations of the near–IR sky brightness (minus zodiacal light) into Galactic stellar and interstellar medium (ISM) components and an extragalactic background. This empirical procedure allows us to estimate the 4.9 μm cosmic infrared background (CIB) as a function of the CIB intensity at shorter wavelengths. A weak indication of a rising CIB intensity at λ > 3.5 μm...

We present an analysis of the properties of the hot interstellar medium (ISM) in the merging pair of galaxies known as The Antennae (NGC 4038/39), performed using the deep, coadded ∼411 ks Chandra ACIS-S data set. These deep X-ray observations and Chandra’s high angular resolution allow us to investigate the properties of the hot ISM with unprecedented spatial and spectral resolution. Through a...

The unprecedented sensitivity of the Spitzer Space Telescope has enabled us for the first time to detect a large sample of Blue Compact Dwarf galaxies (BCDs), which are intrinsically faint in the infrared. In the present paper we present a summary of our findings which providing essential information on the presence/absence of the Polycyclic Aromatic Hydrocarbon features in metal-poor environme...

Many early-type galaxies are detected at 24 to 160μm but the emission is usually dominated by an AGN or heating from the evolved stellar population. Here we present MIPS observations of a sample of elliptical and lenticular galaxies which are rich in cold molecular gas, and we investigate how much of the MIR to FIR emission could be due to star formation activity. The 24μm images show a rich va...

We present an analysis of the rotation measures (RMs) of polarized extragalactic point sources in the Southern Galactic Plane Survey. This work demonstrates that the statistics of fluctuations in RM differ for the spiral arms and the interarm regions. Structure functions of RM are flat in the spiral arms, while they increase in the interarms. This indicates that there are no correlated RM fluct...

D. Lindquist H. Madduri C. J. Paul B. Rajaraman In this paper we describe the IBM Service Management (ISM) architecture, a serviceoriented architecture designed to automate and simplify the management of business services. We describe the four major components of ISM: portal-based user interfaces, a process layer that includes the process runtime and service management solutions, an information...

Many information systems development companies are facing the question on how to apply agile methods in information systems maintenance (ISM). Performing correction of software defects in ISM inevitably degenerates program structure. On the other hand, agile methods provide refactoring to improve program structure without changing its behavior. This paper builds an optimal control model to bala...

There is a strong connection between the formation of a disk galaxy and the properties of the interstellar medium (ISM). Theoretical work has typically either focused on the cosmological buildup of a galaxy with a relatively crude model for the gas physics, or examined local processes in the ISM and ignored the global evolution of the galaxy itself. Here, I briefly review what has been learned ...

I discuss the properties of gas-rich forming galaxies. I particularly emphasize the latest results on Lyα emission that are relevant to the search of distant young galaxies. The interdependance of the Lyα escape with the properties of the ISM in starburst galaxies is outlined. A new model from G. Tenorio-Tagle and his collaborators explain Lyα profiles in starburst galaxies from the hydrodynami...
