Dynamical evidence for intermediate mass black holes in old globular clusters
Michele Trenti
We present an indirect dynamical evidence, based on the measure of the core to half mass radius ratio (rc/rh), that a significant fraction of globular clusters in our galaxy with a…
The Rest-Frame FUV Morphologies of Star-Forming Galaxies at z ~ 1.5 and z ~ 4
J. M. Lotz, P. Madau, M. Giavalisco +2
We apply a new approach to quantifying galaxy morphology and identifying galaxy mergers to the rest-frame far-ultraviolet images of 82 z ~ 4 Lyman break galaxies (LBGs) and 55 1.2…
Lyman alpha emission from local starburst galaxies and high-z objects
G. Ostlin, M. Hayes, J. M. Mas-Hesse +3
We review the history and the current status of the understanding of the processes that regulate Lyman alpha emission from star-forming galaxies. We present some of the most recent…
IMF biases and how to correct them
J. Maíz Apellániz, L. Úbeda, N. R. Walborn +1
We discuss possible sources of biases in the determination of the initial mass function (IMF) introduced by the binning of the data, the uncertainty in the determinations of masses…
Deriving stellar properties from photometry: maximizing information content and minimizing biases
J. Maíz Apellániz
I study the importance of the accurate calibration of photometric systems in order to produce meaningful comparisons between the observed colors + magnitudes and model SEDs. Possib…
Planetary Nebulae in NGC 5128 (Centaurus A)
Eric W. Peng, Holland C. Ford, Kenneth C. Freeman
The study of planetary nebulae (PNe) in the nearby post-merger elliptical galaxy NGC 5128 (Cen A) now has a history of nearly twenty years. As the nearest giant elliptical, it is a…
