We have carried out a complete analysis of the kinematics and the stellar populations of the double-barred S0 galaxy NGC 357. We have measured suitable...

We present preliminary conclusions derived from the analysis of a sample of galactic PNe with [WC]-type central stars (WCPNe) observed with Spitzer/IRS. We...

The Downing Planetarium is the first facility in a new Central California Science Center planned for the California State University, Fresno campus...

According to the current co-evolution picture, most present-day galaxies experienced at least one phase of vigorous black hole (BH) activity in the past, during...

The duration of a starburst is a fundamental parameter affecting the evolution of galaxies yet, to date, observational constraints on the durations of...

We report on the cometary activity of the minor body P/2010 C1 (Scotti), an active Centaur observed at 5.51 AU. The long-term dynamical behavior of this target...

We review the progress of ESO/WFI Imaging and VLT/FLAMES spectroscopy of large numbers of individual stars in nearby dwarf spheroidal galaxies by the Dwarf...

We present the results of a program to derive the complete star-formation history of the Local Group dwarf irregular galaxy Leo A (DDO 69). Leo A is a low...

The Fornax, Virgo, Ursa Major and Perseus galaxy clusters all have very different characteristics, in terms of their density, mass, and large-scale environment...
