A complete 12CO 2-1 map of M51 with HERA
C. Kramer, M. Hitschfeld, K. F. Schuster +2
The nearby, almost face-on, and interacting galaxy M51 offers an excellent opportunity to study the distribution of molecular gas and the mechanisms governing the star formation ra…
A complete 12CO 2-1 map of M51 with HERA: I. Radial averages of CO, HI, and radio continuum
K. F. Schuster, C. Kramer, M. Hitschfeld +2
The mechanisms governing the star formation rate in spiral galaxies are not yet clear. The nearby, almost face-on, and interacting galaxy M51 offers an excellent opportunity to stu…
Study of Photon Dominated Regions in Cepheus B
B. Mookerjea, C. Kramer, M. Roellig +1
Aim: The aim of the paper is to understand the emission from the photon dominated regions in Cepheus B, estimate the column densities of neutral carbon in bulk of the gas in Cepheu…
A KOSMA 7 deg^2 13CO 2--1 & 12CO 3--2 survey of the Perseus cloud
K. Sun, C. Kramer, V. Ossenkopf +3
Characterizing the spatial and velocity structure of molecular clouds is a first step towards a better understanding of interstellar turbulence and its link to star formation. We p…
