Central Molecular Zone H2CO temperature maps
The Galactic center is the closest region in which we can study star formation under extreme physical conditions like those in high-redshift galaxies. We measure the temperature... -
SiO in ATLASGAL-selected massive clumps
The processes leading to the birth of high-mass stars are poorly understood. The key first step to reveal their formation processes is characterising the clumps and cores from... -
Vilnius photometry of TGU H994 P1
The results of CCD photometry in the seven-color Vilnius system are given for 855 stars down to V~20mag in three 12x12 arcmin areas of the dark cloud TGU H994P1. Observational... -
N131 bubble CO integrated intensity maps
OB-type stars have strong ionizing radiation and drive energetic winds. The ultraviolet radiation from ionizing stars may heat dust and ionize gas to sweep up an expanding... -
NGC253 near-infrared H_2_ emission
Because of its large angular size and proximity to the Milky Way, NGC 253, an archetypal starburst galaxy, provides an excellent laboratory to study the intricacies of this... -
Heiles Cloud 2 CH radio emission
A mapping observation of the J=1/2 {Lambda}-type doubling transition (3.3GHz) of CH has been conducted toward Heiles Cloud 2 (HCL2) in the Taurus molecular cloud complex to... -
Chamaeleon III 870um sources maps
The nearby Chamaeleon molecular cloud complex is a good laboratory for studying the process of low-mass star formation because it consists of three clouds with very different... -
^12^C^18^O(3-2) map of rho Oph A
The large submillimetre map of rho Oph A in the ^12^C^18^O(3-2) line, obtained with the APEX 12m telescope, covers 10' in RA by 5' in DE, sampled on a rectangular grid, aligned... -
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... -
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... -
Interstellar ^12^C/^13^C ratios
The ^12^C/^13^C isotope ratio is a tracer of stellar yields and the efficiency of mixing in the ISM. ^12^CH^+^/^13^CH^+^ is not affected by interstellar chemistry, and is the... -
Rest frequencies of methanol maser lines
We report accurate laboratory measurements of selected methanol transition frequencies between 0.834 and 230GHz in order to facilitate astronomical velocity analyses. New data... -
H_2_ flows in rho Ophiuchi A
We present an unbiased search for molecular hydrogen emission in the L1688 cloud within the rho Ophiuchi molecular cloud complex. Our near-infrared survey covers a connected... -
IRAM NOEMA CO(1-0) cubes for IC342
We present a new wide-field 10.75x10.75arcmin^2^ (~11x11kpc^2^), high-resolution (theta=3.6"~60pc) NOEMA CO(1-0) survey of the very nearby (d=3.45Mpc) spiral galaxy IC 342. The... -
Laboratory spectroscopy of isobutene
Isobutene ((CH_3_)2_C=CH_2) is one of the four isomers of butene (C_4_H_8_). After the detection of propene (CH_3_CH=CH_2_) toward TMC-1, and also in the warmer environment of... -
3{mu}m survey of the Chamaeleon I dark cloud
We describe an L-band photometric survey of ~0.5deg^2^ of the Chamaeleon I dark cloud. The survey has a completeness limit of L<11.0. Our survey detects 124 sources,... -
OB stars in N206 in the LMC
Context. Clusters or associations of early-type stars are often associated with a "superbubble" of hot gas. The formation of such superbubbles is caused by the feedback from... -
NIKA view of two star-forming IRDCs
The thermal emission of dust grains is a powerful tool for probing cold, dense regions of molecular gas in the interstellar medium, and so constraining dust properties is key to... -
Molecular cloud in Corona Australis
We present a catalogue of prestellar and starless cores within the Corona Australis molecular cloud using photometric data from the Herschel Space Observatory. At a distance of... -
IRDC18223 images
Filamentary structures in the interstellar medium are crucial ingredients of the star formation process. They fragment to form individual star-forming cores, and at the same...
