Secular variation on the territory of the Czech Republic and reduction of the magnetic survey to the epoch 2010.5
Magnetis survey Secular variation Repeat stations
font style='font-size:12px;'>
2015/8/26
A recent stage of the magnetic surveying activities in the Czech Republic was started in the fifties by setting up a basic network of the first order. It consists of 199 points. Complete measurements ...

2015/8/26
The results of geomagnetic field components of the renewed Ukrainian repeat stations (RS) network are presented. The methods of absolute geomagnetic and astro-geodetic measurements are described. The ...
The pulsar B2224+65 and its jets: a two epoch X-ray analysis
X-ray B2224+65
font style='font-size:12px;'>
2014/12/22
We present an X-ray morphological and spectroscopic study of the pulsar B2224+65 and its apparent jet-like X-ray features based on two epoch Chandra observations. The main X-ray feature, which shows a...

Intensity Mapping Fine Structure Line during Epoch Reionization
font style='font-size:12px;'>
2011/10/11
The atomic CII fine-structure line is one of the brightest lines in a typical star-forming galaxy spectrum with a luminosity ~ 0.1% to 1% of the bolometric luminosity. It is potentially a reliable tra...
Spectroscopic confirmation of z~7 LBGs: probing the earliest galaxies and the epoch of reionization
Spectroscopic confirmation earliest galaxies epoch reionization
font style='font-size:12px;'>
2011/9/29
We present the final results from our ultra-deep spectroscopic campaign with FORS2 at the ESO/VLT for the confirmation of z~7 "z--band dropout" candidates selected from our VLT/Hawk-I imaging survey o...
Spectral variability of quasars from multi-epoch photometric data in the Sloan Digital Sky Survey Stripe 82
Spectral variability multi-epoch photometric data
font style='font-size:12px;'>
2011/1/11
We present a new approach to analysing the dependence of quasar variability on rest-frame wavelengths. We exploited the spectral archive of the Sloan Digital Sky Survey (SDSS) to create a sample of mo...
Extrapolating the Evolution of Galaxy Sizes to the Epoch of Reionization

font style='font-size:12px;'>
2010/11/16
We use data on the high-redshift evolution of the size distribution and luminosity function of galaxies to constrain the relationship between their star formation eciency and starburst lifetime. Base...

2010/11/11
The Multi-Epoch Nearby Cluster Survey (MENeaCS) has discovered twenty-two cluster Type Ia
supernovae (SNe) in the 58 X-ray selected galaxy clusters (0.05. z .0.15) surveyed. Four of our
SN Ia events...
Quantifying the Imprecision of Accretion Theory and Implications for Multi-Epoch Observations of Protoplanetary Discs

font style='font-size:12px;'>
2010/12/27
If accretion disc emission results from turbulent dissipation, then axisymmetric accretion theory must be used as a mean field theory: turbulent flows are at most axisymmetric only when suitably avera...
LambdaCDM epoch reconstruction from F(R,G) and modified Gauss-Bonnet gravities
Gauss-Bonnet gravities LambdaCDM epoch F(R,G)
font style='font-size:12px;'>
2010/3/18
Dark energy cosmology is considered in a modified Gauss-Bonnet model of gravity with and without a scalar field. It is shown that these generalizations of General Relativity endow it with a very rich ...
