10 Sep 2020 | | Abstract: | The latest generation of Galactic-plane surveys is enhancing our ability to
study the effects of galactic environment upon the process of star formation.
We present the first data from CO Heterodyne Inner Milky Way Plane Survey 2
(CHIMPS2). CHIMPS2 is a survey that will observe the Inner Galaxy, the Central
Molecular Zone (CMZ), and a section of the Outer Galaxy in $^{12}$CO,
$^{13}$CO, and C$^{18}$O $(J = 3
ightarrow2)$ emission with the Heterodyne
Array Receiver Program on the James Clerk Maxwell Telescope (JCMT). The first
CHIMPS2 data presented here are a first look towards the CMZ in $^{12}$CO J =
3$
ightarrow$2 and cover $-3^{circ}leq,ell,leq,5^{circ}$ and
$mid$b$mid leq 0.5^{circ}$ with angular resolution of 15 arcsec, velocity
resolution of 1 km s$^{-1}$, and rms $Delta T_A ^ast =$ 0.58 K at these
resolutions. Such high-resolution observations of the CMZ will be a valuable
data set for future studies, whilst complementing the existing Galactic Plane
surveys, such as SEDIGISM, the Herschel infrared Galactic Plane Survey, and
ATLASGAL. In this paper, we discuss the survey plan, the current observations
and data, as well as presenting position-position maps of the region. The
position-velocity maps detect foreground spiral arms in both absorption and
emission. | | Source: | arXiv, 2009.05073 | | Services: | Forum | Review | PDF | Favorites | |
