Very Large Telescope adaptive optics images of NGC 253 with resolutions down to 200 mas resolve the central 300 pc of this galaxy in ∼37 infrared (IR) bright knots, a factor of 3 larger than previously reported and extended diffuse emission. The angular resolution, comparable to that of available Very Large Array 2 cm maps, permits us a very accurate IR-radio registration. Eight radio sources are found to have an IR counterpart. The knots have Hα equivalent width of about 80 A, sizes of ∼3 pc… Expand

The most recent burst of star formation in the massive elliptical galaxy NGC 1052
High spatial resolution near-infrared (NIR) images of the central 24 x 24 arcsec(2) (similar to 2 x 2 kpc(2)) of the elliptical galaxy NGC 1052 reveal a total of 25 compact sources randomlyExpand
Forming Super Star Clusters in the Central Starburst of NGC 253
NGC 253 hosts the nearest nuclear starburst. Previous observations show a region rich in molecular gas, with dense clouds associated with recent star formation. We used ALMA to image the 350 GHz dustExpand
The central parsecs of active galactic nuclei: challenges to the torus
Type 2 AGN are by definition nuclei in which the broad-line region and continuum light are hidden at optical/UV wavelengths by dust. Via accurate registration of infrared (IR) Very Large TelescopeExpand
Unveiling Extragalactic Star Formation Using Radio Recombination Lines: An Expanded Very Large Array Pilot Study with NGC 253
Radio recombination lines (RRLs) are powerful, extinction-free diagnostics of the ionized gas in young, star-forming regions. Unfortunately, these lines are difficult to detect in external galaxies.Expand
