The dependence of HII region properties on global and local surface brightness within galaxy discs
J. F. Helmboldt, R. A. M. Walterbos, G. D. Bothun +2
Using B, R, and H-alpha images of roughly equal-sized samples of low surface brightness (LSB) and high surface brightness (HSB) galaxies (~40 galaxies apiece), we have explored the…
Current star formation in early-type galaxies and the K+A phenomenon
J. F. Helmboldt, R. A. M. Walterbos, T. Goto
We present the results of an effort to identify and study a sample of the likely progenitors of elliptical (E) and lenticular (S0) K+A galaxies. To achieve this, we have searched a…
The Stellar Mass Distribution in the Giant Star Forming Region NGC 346
E. Sabbi, M. Sirianni, A. Nota +8
Deep F555W and F814W Hubble Space Telescope ACS images are the basis for a study of the present day mass function (PDMF) of NGC346, the largest active star forming region in the Sm…
Progressive star formation in the young SMC cluster NGC 602
Lynn Redding Carlson, E. Sabbi, M. Sirianni +9
NGC 602 is a young stellar cluster located in a peripheral region of the Small Magellanic Cloud known as the wing. Far from the main body of the galaxy and abutting the Magellanic…
Bar imprints on the inner gas kinematics of M33
Edvige Corbelli, Rene' A. M. Walterbos
We present measurements of the stellar and gaseous velocities in the central 5' of the Local Group spiral M33. The data were obtained with the ARC 3.5m telescope. Blue and red spec…
Past and present star formation in the SMC: NGC 346 and its neighborhood
E. Sabbi, M. Sirianni, A. Nota +8
In the quest of understanding how star formation occurs and propagates in the low metallicity environment of the Small Magellanic Cloud (SMC), we acquired deep F555W (~V), and F814…
