We report the detection of a deep (C I) absorption feature at km s~1 with a line 3P1] 3P0 vLSR \ 12 width of 6 km s~1 toward extended line emission at a distance of 11@ from Sgr C. The 492 GHz observations were made with the Antarctic Submillimeter Telescope and Remote Observatory. The absorption feature allows the derivation of lower limits for the C I column density in the cold foreground mat...

We present ALMA data on the 3mm continuum emission, CO isotopologues (12CO, 13CO, C18O), and high-density molecular tracers (HCN, HCO+, HNC, HNCO, CS, CN, CH3OH) in NGC4526. These enable a detailed study of physical properties gas longtime resident Virgo Cluster; comparisons to more commonly-studied spiral galaxies offer intriguing hints into processing cluster environment. Many line ratios NGC...

We present an XMM-Newton observation of the long-overlooked radio source G350.1–0.3. The X-ray spectrum of G350.1–0.3 can be fit by a shocked plasma with two components: a high-temperature (1.5 keV) region with a low ionization time scale and enhanced abundances, plus a cooler (0.36 keV) component in ionization equilibrium and with solar abundances. The X-ray spectrum and the presence of non-th...

We present sub-arcsecond, Multi-Element Radio Linked Interferometer (MERLIN) observations of the decimetre radio continuum structure and neutral hydrogen (H) absorption from the nuclear region of the starburst galaxy NGC 4194 (the Medusa Merger). The continuum structure of the central kiloparsec of the Medusa has been imaged, revealing a pair of compact radio components surrounded by more diff...

Aims. We investigate the physical properties and spatial distribution of Carbon Monoxide (CO) gas in the disks around the Herbig Ae/Be stars HD 97048 and HD 100546. Methods. Using high-spectral-resolution 4.588−4.715 μm spectra containing fundamental CO emission taken with CRIRES on the VLT, we probe the circumstellar gas and model the kinematics of the emission lines. By using spectro-astromet...

Aims. We present X-ray and 12CO(J=1–0) observations of the very-high-energy (VHE) γ-ray source HESS J1813–178 with the aim of understanding the origin of the γ-ray emission. Methods. High-angular resolution X-ray studies of the VHE γ-ray emission region are performed using 18.6 ks of XMM-Newton data, taken on HESS J1813–178 in October 2005. Using this dataset we are able to undertake spectral a...
