... M81: A Bulging Spiral Galaxy . ... Credit: NASA , UIT Explanation: Few stars are still forming in the old giant spiral galaxy M81. The blue regions in this picture - representing ultraviolet light - highlight regions of bright young stars and star formation and appear rare than in M74 and M33 . ... M81 is therefore classified as spiral galaxy type "Sab" on the Hubble Sequence of Galaxies . ... Bright Spiral Galaxy M81 from Hubble . Bright Spiral Galaxy M81 in Ultraviolet from Galex . ...

We present our analysis of UV attenuation by internal dust of a large sample (N=906 galaxies) of Lyman break galaxies (LBGs). Using spectral energy distributions (SEDs) from the PУ?GASE galaxy spectral evolution model, we apply dust attenuation corrections to the G-R colors, using the Witt Gordon models for radiative transfer in dusty galactic environments to arrive at the UV attenuation factors. ...

... Previous: Substepping and its Application to HST Imaging . ... This is a preliminary report on an application of the co-addition technique based upon the Richardson-Lucy algorithm. The combination of high signal-to-noise ground-based images obtained with the ESO NTT using SUSI with high angular resolution HST FOC f/96 images gives new insights on the properties of galaxy cores and their potential time variability. Cores of galaxies are one of the main thrusts of present extragalactic research. ...
