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. ...

For around forty years, astrophysicists have observed the annihilation of positrons in the Galaxy at a prodigious rate. ... The fact the Galactic bulge far outshines the disk in annihilating positrons which are injected into the ISM at low energies makes the source of the positrons difficult to identify, as the main source of such positrons are prima facie located in the Galactic disk. ...

... Chandra Observation of LMXB in M84 . We present characteristics of the X-ray point source population in the M84 field as observed by Chandra ACIS-S. We find the galactic sources in M84 follow the stellar light profile, which imposes similar formation histories for stars in both single and binary systems. After correcting for incompleteness in the source detection, we find a log N-log S similar to that of the elliptical galaxy NGC4697. ...
