Using UV-to-H broad and narrow-band HST imaging, we derive the ages and masses of the 11 brightest star clusters in the dwarf galaxy NGC5253. This galaxy...
We report on a sudden brightening of the dwarf nova WZ Sge during decline from outburst (cf. IAUC #7669, IAUC #7670). The observations were made with the 0.82-m...
Broad band energy spectrum and a low frequency QPO from H1743-322 in the hard state revealed by INTEGRAL and Swift observations
Following the report of renewed activity of the microquasar H1743-322 (aka IGR J17464-3213, ATels #3263, #3267) we have triggered a Swift ToO. The observation...
Broad relativistic iron line observed in SAX J1808.4-3658 by Suzaku
The accreting millisecond X-ray pulsar SAX J1808.4-3658 recently exhibited another outburst in September and October 2008 (ATel #1728). During this outburst, on...
Broad-band spectral properties of absorbed BLAGN from the 2XMMi-SDSS catalogues
We present results for a sample of absorbed Broad-line Active Galactic Nuclei (BLAGN) se-lected from a cross-correlation of the 2XMMi and Sloan Digital Sky...
Brown dwarf candidates from the PennState-Toruń Planet Search with the Hobby-Eberly Telescope .
We present preliminary results of a brown dwarf (BD) detection in a ˜1000 star sample monitored with the ongoing PennState-Toruń Centre for Astronomy Planet...
Brown dwarf census with the Dark Energy Survey year 3 data and the thin disk scale height of early L types
We present a catalogue of 11,745 brown dwarfs with spectral types ranging from L0 to T9, photometrically classified using data from the Dark Energy Survey (DES)...
