The Dense Gas in the Central Kiloparsec of NGC 6946
E. S. Levine, Tamara T. Helfer, R. Meijerink +1
We present observations of the HCN and HCO+ J=1-0 transitions in the center of the nearby spiral galaxy NGC 6946 made with the BIMA and CARMA interferometers. Using the BIMA SONG C…
Thermal and non-thermal components of the interstellar medium at sub-kiloparsec scales in galaxies
R. Paladino, M. Murgia, T. T. Helfer +5
Aims: We present new radio continuum observations of ten BIMA SONG galaxies, taken at 1.4 GHz with the Very Large Array. These observations allow us to extend the study of the rela…
The Molecular Connection to the FIR-Radio Continuum Correlation in Galaxies
M. Murgia, T. T. Helfer, R. Ekers +4
We have studied the relationships between the radio continuum (RC) and CO emission for a set of galaxies selected from the BIMA Survey of Nearby Galaxies. We find that the global C…
Molecular gas and star formation in BIMA SONG bars
Kartik Sheth, Stuart N. Vogel, Andrew I. Harris +6
Using a sample of 7 barred spirals from the BIMA Survey of Nearby Galaxies (SONG), we compare the molecular gas distribution in the bar, to recent massive star formation activity.…
High Resolution BIMA Observations of CO, HCN, and 13CO in NGC 1068
Tamara T. Helfer, Leo Blitz
We present high-resolution CO, HCN, and 13CO maps of the inner arcminute of NGC 1068 made with the BIMA interferometer. Several features appear in the CO map which have not previou…
