We present ultraviolet, optical, near-infrared, Spitzer mid-infrared, and radio images of 14 radio-selected objects in M33. ... We have detected the majority of cluster candidates in M33 at all wavelengths. ... These results suggest that 11 of the 14 radio-selected objects are optically visible young star clusters with a surrounding H II region, that 2 are background objects, possibly active galactic nuclei (AGNs), and that 1 is a Wolf-Rayet star with a surrounding H II region. ...

... Colours of stars and galaxies hold information on intrinsic and extrinsic parameters, such as stellar temperatures and galaxy populations, selective absorption and colour changes due different dust contents and inclination angles of galaxies, as well as galaxy redshifts and evolution. ... The colour magnitude diagram of 65000 galaxies to which all above-mentioned quantities and others contribute can only be explained by comparison with simulations. ... Colours are also of technical help. ...

Next: The APM selected sample Up: Second priority candidates Previous: Second priority candidates . From the random selected subsample of second priority candidates we observed twenty six objects during the 6-m telescope runs (mainly those with R.A.< 11 h ) along with the observations of first priority targets. Altogether we found 12 emission-line objects: one appeared to be a QSO with z =3.15, and the rest are various types of ELGs. ... One object is an absorption-line galaxy. ...

... We have developed a web site using HTML, Php, Python, and MySQL that extracts, processes, and displays data from the Sloan Digital Sky Survey (SDSS) and the Two-Micron All-Sky Survey (2MASS). The goal is to locate brown dwarf candidates in the SDSS database by looking at color cuts; however, this site could also be useful for targeted searches of other databases as well. MySQL databases are created from broad searches of SDSS and 2MASS data. ... 2002). ... 2002, AJ, 123, 3409 . ...

... The numbers of three types of compact binaries containing accreting NSs and BHs, which are most interesting from the point of view of their observational appearances, have been calculated as a function of time: i) X-ray transient source containing a NS in an eccentric orbit around a main sequence Be-star (the observed prototype: A0535+26), ii) BH The evolution of the selected types of X-ray binaries during the first 10 million years after the starburst onset is presented in Fig. ...

... ASAP contains flexible data selection. Data can be selected based on IF, beam, polarisation, scan number as well as values such as Tsys. ... Selection is based on a selector object. This object is created and various selection functions applied to it ( set_ifs , set_beams etc). The selection object then must be applied to a scantable using the set_selection function. ... The selection can then be reset and all spectra are visible. ... Select by source name. ... Select data based on Tsys. ...
