Boxy/peanut bulges in disk galaxies have been associated to stellar bars. In this talk, we discuss the different properties of such bulges and their relation...

In the standard cosmological model of galaxy evolution, mergers and interactions play a fundamental role in shaping galaxies. Galaxies that are currently...

Departures from a simple exponential decay (usually called breaks or truncations) in the surface brightness distribution of galaxy disks are found in the vast...

A search for bright galaxies associated with radio sources from the Westerbork Northern Sky Survey (WENSS) minisurvey has been carried out. A galaxy counterpart...

Two of us (M.M. and J.A.L.A.) imaged five galaxy clusters with the 2.5m Nordic Optical Telescope (NOT) located at the Roque de Los Muchachos Observatory (La...

The new X-ray transient MAXI J1836-194 is a black hole candidate X-ray binary (BHXB; ATel #3611, #3613, #3628 #3652). Its X-ray spectrum was seen to soften...

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...

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...
