AN INVESTIGATION OF THE DUST CONTENT IN THE GALAXY PAIR NGC 1512/1510 FROM NEAR-INFRARED TO MILLIMETER WAVELENGTHS
IRAC MIPS
2014/12/22
We combine new ASTE/AzTEC 1.1 mm maps of the galaxy pair NGC 1512/1510 with archival Spitzer IRAC and MIPS images covering the wavelength range 3.6-160 μm from the SINGS project. The availability of t...
The stellar and gaseous content of massive low surface brightness disk galaxies
Multiple wavelength Subset. Extreme type Galaxy Atomic gas Spiral galaxies
2014/12/9
This dissertation presents a multi-wavelength study of a subset of an extreme type of galaxy, those which have low surface brightnesses large disks, and large amounts of atomic gas, yet which have tot...

The Cold Gas Content of Bulgeless Dwarf Galaxies
galaxies: dwarf– galaxies: evolution – galaxies: formation – methods:N-body simulations
2011/10/9
We present an analysis of the neutral hydrogen (HI) properties of a fully cosmological hydrodynamical dwarf galaxy, run with varying simulation parameters. As reported by Governato et al. (2010), the ...
On the redshift-evolution of the Lyman-alpha escape fraction and the dust content of galaxies
the redshift-evolution the Lyman-alpha escape fraction
2011/1/10
The Ly-alpha emission line has been proven a powerful tool by which to study evolving galaxies at the highest redshifts. However, in order to use Lya as a physical probe of galaxies, it becomes vital ...
Metallicities and dust content of proximate damped Lyman alpha systems in the Sloan Digital Sky Survey
Metallicities dust content proximate damped Lyman alpha systems
2011/1/11
Composite spectra of 85 proximate absorbers (log N(HI)>20 and velocity difference between the absorption and emission redshift, dv<10,000 km/s) in the SDSS are used to investigate the trends of metal ...
The Massive Star Content of Circumnuclear Star Clusters in M83
ircumnuclear Star Clusters
2010/11/16
The circumnuclear starburst of M83 (NGC 5236), the nearest such example (4.6 Mpc), constitutes an ideal site for studying the massive star IMF at high metallicity (12+log[O/H]=9.1±0.2, Bresolin & Kenn...
The Origin of Dust in the Early Universe: Probing the Star Formation History of Galaxies by their Dust Content
galaxies evolution high-redshift starburst - quasars individ-ual
2010/11/11
Two distinct scenarios for the origin of the ∼ 4 × 108 M⊙ of dust observed in the high-redshift (z = 6.4) quasar J1148+5251 have been proposed. The first assumes that this galaxy is much younger...
We analyse the stellar and hot gas content of 18 nearby, low-mass galaxy clusters, detected in
redshift space and selected to have a dynamical mass 3 × 1014 < M/M⊙ < 6 × 1014 (h =0.7), as measured fr...

Instrumentation and Methods for Astrophysics (astro-ph.IM)
2011/1/7
In spectral studies of water vapor under laboratory conditions (determination of molecular constants, measurement for spectral transmission functions), the amount of water vapor in the time of the mea...
The Laboratory Complex for the Calibration of Photometers Using the Optical Method for Determination of the Water Vapor Content in the Earth Atmosphere
Instrumentation and Methods for Astrophysics (astro-ph.IM)
2011/1/7
We describe the laboratory complex for the calibration of photometers that are used in weather service to measure the water vapor content in the Earth atmosphere.

The HI Content of the Eridanus Group of Galaxies
evolution galaxies clusters individual Eridanus radio lines
2009/5/12
TheHI content of galaxies in the Eridanus group is studied using
the GMRT observations and the HIPASS data. A significant HI deficiency
up to a factor of 2–3 is observed in galaxies in the high gala...
