VLA NH3 observations of 5 IRAS sources
The high angular resolution images with the Very Large Array (VLA) allow us to explore the general properties of protostellar cores in massive star forming regions at large... -
Dense cores in interstellar molecular clouds
Stars form in the cold dense cores of interstellar molecular clouds and the detailed knowledge of the spectrum of masses of such cores is clearly a key for the understanding of... -
JHK photometry near IRAS 06145+1455
Our goal in this paper is to study stars and molecular gas in the direction of IRAS 06145+1455 (WB89-789). The kinematic distance of the associated molecular cloud is 11.9kpc.... -
Velocities of OMC-1 flows
Observations are reported of H_2_ IR emission in the S(1) v=1-0 line at 2.121{mu}m in the Orion Molecular Cloud, OMC1, using the GriF instrument on the Canada-France-Hawaii... -
Star formation in Perseus. II.
Hatchell et al. (2005, Cat. , Paper I) published a submillimetre continuum map of the Perseus molecular cloud, detecting the starless and protostellar cores within it. The aim... -
XMM Optical Monitor Survey of TMC
The Optical Monitor (OM) on-board XMM-Newton obtained optical/ultraviolet data for the XMM-Newton Extended Survey of the Taurus Molecular Cloud (XEST), simultaneously with the... -
Spitzer mid-IR spectra of 3 molecular clouds
This work was conducted as part of the SPECPDR program, dedicated to the study of very small particles and astrochemistry, in Photo-Dissociation Regions (PDRs). We present the... -
WFI optical photometry in Cha II dark cloud
We present the results of an optical multi-band survey for low-mass pre-main sequence (PMS) stars and young brown dwarfs (BDs) in the Chamaeleon II (Cha II) dark cloud. This... -
SIMBA observations of SMC
CO observations have been the best way so far to trace molecular gas in external galaxies, but in low metallicity environments the gas mass deduced could be largely... -
JHKs photometry of a new stellar cluster
We report the discovery of a new young stellar cluster and molecular cloud located in the far outer Galaxy, seen towards IRAS 06361-0142, and we characterise their properties.... -
N2H+(1-0) maps of Ophiuchus main cloud
The earliest phases of clustered star formation and the origin of the stellar initial mass function (IMF) are currently much debated. In order to constrain the origin of the... -
A search for pre-biotic molecules
Low-noise, 0.8MHz resolution spectra around 90GHz towards four hot core sources: Orion KL, W51 e1/e2, S140, and W3(OH), are presented. The observations were performed using the... -
Millimeter continuum mapping of Cygnus X
We report on a millimeter continuum survey of the entire Cygnus X molecular complex. We used the MAMBO and MAMBO-2 bolometer arrays on the IRAM 30m telescope to map a 3deg^2^... -
HK photometry of rho Oph PMS stars
Variability is a common characteristic of pre-main-sequence stars (PMS). Near-IR variability surveys of young stellar objects (YSOs) can probe stellar and circumstellar... -
The RMS survey: ^13^CO observations of YSOs
MSX names, positions, observational rms values and molecular line parameters obtained from Gaussian fits to all detected components made towards the RMS sample of massive young... -
M83 volume densities of giant molecular clouds
Using observed GALEX far-ultraviolet (FUV) fluxes and VLA images of the 21-cm HIcolumn densities, along with estimates of the local dust abundances, we measure the volume... -
Young T Tauri star in CB 26 molecular outflows
The disk-outflow connection is thought to play a key role in extracting excess angular momentum from a forming proto-star. Although jet rotation has been observed in a few... -
Molecular hydrogen flows along Ori A cloud
A census of molecular hydrogen flows across the entire Orion A giant molecular cloud is sought. With this paper we aim to associate each flow with its progenitor and associated... -
Embedded sources in L 1688
The Ophiuchus clouds, in particular L 1688, are an excellent region to study the embedded phases of star formation, due to the relatively large number of protostars. However,... -
1.2mm maps of southern Infrared Dark Clouds
What are the mechanisms by which massive stars form? What are the initial conditions for these processes? It is commonly assumed that cold and dense Infrared Dark Clouds (IRDCs)...
