We present a catalog of 4780 extended sources from the outer field of M33. The catalog includes 73 previously identified clusters or planetary nebulae, 1153 likely background galaxies, and 3554 new candidate stellar clusters. The survey is based on deep ground-based images obtained with the MegaCam instrument on the CFHT telescope. We provide gri photometry for detected objects as well as estim...

Let G be a group of permutations acting on an n-vertex set V , and X and Y be two simple graphs on V . We say that X and Y are Gisomorphic if Y belongs to the orbit of X under the action of G. One can naturally generalize the reconstruction problems so that when G is Sn, the symmetric group, we have the usual reconstruction problems. In this paper, we study G-edge reconstructibility of graphs. ...

Given a set C of binary n-tuples and c ∈ C, how many bits of c suffice to distinguish it from the other elements in C ? We shed new light on this old combinatorial problem and improve on previously known bounds.

We report evidence for a recent burst of star formation located within 9 pc of the active nucleus of NGC 1097. The observational signatures of the starburst include UV absorption lines and continuum emission from young stars observed in a small-aperture HST spectrum. The burst is ≤ a few × 10 6 yr old, has a mass of ∼ 10 6 M ⊙ , an observed luminosity of 1.5 × 10 7 L ⊙ and is obscured by A V ≈ ...

We present a new (V,B-V) Color-Magnitude Diagram (CMD) of the Carina dwarf spheroidal (dSph) that extends from the tip of the Red Giant Branch (RGB) down to V ∼ 25 mag. Data were collected with the Wide Field Imager (WFI) available at 2.2m ESO/MPI telescope and cover an area of ≈ 0.3 degree 2 around the center of the galaxy. We confirm the occurrence of a substantial amount of old stars with ag...
