We predict the behaviour of the abundances of ff- elements and iron in the intracluster medium (ICM) as a function of redshift in poor and rich clusters. In order to do that we calculate the detailed chemical evolution of elliptical galaxies by means of on ...
Reactions of tBuP(NH2)2 with Group 13 trialkyls MR3 (M = Al, Ga, In; R = Me, tBu) were investigated in detail. According to variable-temp. (VT) NMR investigations, the reaction proceeds stepwise with the initial formation of aminophosphane adducts, which s ...
We report the first results of a spectroscopic search for Ly alpha envelopes around three z similar to 4.5 radio-quiet quasars. Our observational strategy adopts the FORS2 spectrograph mounted to the UT1 of the Very Large Telescope (VLT) in the multi-slit ...
We present a high-resolution dark matter reconstruction of the z = 0.165 Abell 901/902 supercluster from a weak lensing analysis of the Hubble Space Telescope STAGES survey. We detect the four main structures of the supercluster at high significance, resol ...
Using angle-resolved photoemission spectroscopy we demonstrate that a normal-state pseudogap exists above TN-IC in one of the most studied two-dimensional charge-density wave (CDW) dichalcogenides 2H-TaSe2. The initial formation of the incommensurate CDW i ...
We conducted an exploratory search for quasars at z similar to 6-8, using the Early Data Release (EDR) from the United Kingdom Infrared Deep Sky Survey (UKIDSS) cross-matched to panoramic optical imagery. High-redshift quasar candidates are chosen using mu ...
We present K-band data for the brightest cluster galaxies (BCGs) from the ESO Distant Cluster Survey (EDisCS). These data are combined with the photometry published by Aragon Salamanca, Baugh & Kauffmann and a low-redshift comparison sample built from the ...
The absorbance signal in electrothermal at. absorption spectrometry is a result of the processes of atom formation and dissipation and 1st of all depends on the initial generation of atoms from the surface. The rising part of the absorbance time profiles c ...
The coordination and cooperation strategies of Micro Aerial Vehicles (MAVs) become increasingly popular to carry out high-level, complex tasks such as object transporta- tion, patrolling, inspection robustly and with high performance. One of the crucial co ...
