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...
Investigation of Herbig Ae /Be stars in the near -infrared with a long baseline interferometer
Long baseline Stars Near infrared interferometry The dust
2014/12/9
We have conducted the first systematic study of Herbig Ae/Be stars using the technique of long baseline spatial interferometry in the near-infrared, with the objective of characterizing the distributi...
Investigation of symmetries and conserved charges in general relativity
The vector of gravity The black hole mechanics The first law Accelerate the black hole A black hole. Static fixation Bubble time and space
2014/12/9
This thesis presents a series of results relating to conserved charges in general relativity. In particular, we give a general expression for a gravitational charge corresponding to a boost Killing ve...
The Gamma-Ray Blazar PKS 0208-512, a Multi-Wavelength Investigation
Gamma-Ray Blazar PKS 0208-512 Multi-Wavelength Investigation
2012/2/23
The gamma-ray blazar PKS 0208-512 has shown strong periods of flaring, at all frequencies from radio to gamma-ray. This has led to its inclusion in the TANAMI project, which tracks the jets of souther...
Investigation of the errors in SDSS proper-motion measurements using samples of quasars
Investigation of the errors in SDSS proper-motion measurements using samples of quasars
2011/10/17
We investigate in detail the probability distribution function (pdf) of the proper-motion measurement errors in the SDSS+USNO-B proper-motion catalog of \citet{mun04} using clean quasar samples. The p...
An investigation into the MOPED data compression algorithm
the MOPED data compression algorithm Astrophysics
2011/1/13
We investigate the use of the MOPED algorithm (\cite{MOPED1}) for data compression and faster evaluation of likelihood functions. Since MOPED only guarantees maintaining the Fisher matrix of the likel...
Investigation for the enrichment pattern of the element abundances in r+s star HE 0338-3945: a special r-II star?
the enrichment pattern the element abundances r+s star HE 0338-3945
2011/1/10
The very metal-poor star HE 0338-3945 shows a double-enhanced pattern of the neutron-capture elements. The study to this sample could make people gain a better understanding of s- and r-process nucleo...
Investigation of Dynamics of Self-Similarly Evolving Magnetic Clouds
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/7
Magnetic clouds (MCs) are "magnetized plasma clouds" moving in the solar wind. MCs transport magnetic flux and helicity away from the Sun. These structures are not stationary but feature temporal evol...
An investigation of the close environment of beta Cep with the VEGA/CHARA interferometer
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/28
High-precision interferometric measurements of pulsating stars help to characterize their close environment. In 1974, a close companion was discovered around the pulsating star beta Cep using the spec...
Investigation of the hadronic interaction models using WILLI detector
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/27
The WILLI detector, built in IFIN-HH Bucharest, in collaboration with KIT Karlsruhe, is a rotatable modular detector for measuring charge ratio for cosmic muons with energy $<$ 1 GeV. It is under cons...
