Dense Gas Fraction and Star Formation Efficiency Variations in the Antennae Galaxies
Frank Bigiel, Adam K. Leroy, Leo Blitz +5
We use the CARMA millimeter interferometer to map the Antennae Galaxies (NGC4038/39), tracing the bulk of the molecular gas via the 12CO(1-0) line and denser molecular gas via the…
Clustered Cepheid Variables 90 kiloparsec from the Galactic Center
Sukanya Chakrabarti, Roberto Saito, Alice Quillen +3
Distant regions close to the plane of our Galaxy are largely unexplored by optical surveys as they are hidden by dust. We have used near-infrared data (that minimizes dust obscurat…
Giant Molecular Clouds in the Early-Type Galaxy NGC4526
Dyas Utomo, Leo Blitz, Timothy Davis +4
We present a high spatial resolution ( pc) of CO() observations of the lenticular galaxy NGC4526. We identify 103 resolved Giant Molecular Clouds (GMCs) and…
The Atlas3D Project - XXX. Star formation histories and stellar population scaling relations of early-type galaxies
Richard M. McDermid, Katherine Alatalo, Leo Blitz +20
We present the stellar population content of early-type galaxies from the Atlas3D survey. Using spectra integrated within apertures covering up to one effective radius, we apply tw…
