A high sensitivity HI survey of the sky at δ ≤ -25°

Arnal, Edmundo Marcelo; Bajaja, Esteban; Larrarte, Juan José; Morras, Ricardo; Pöppel, W. G. L. (2000)

A massive prestellar clump hosting no high-mass cores

Sanhueza, Patricio; Jackson, James; Zhang, Qizhou; Guzmán Fernández, Andrés; Lu, Xing; Stephens, Ian W.; Wang, Ke; Tatematsu, Ken'ichi (IOP Publishing, 2017-06-01)

The infrared dark cloud (IRDC) G028.23-00.19 hosts a massive (1500M(circle dot)), cold (12 K), and 3.6-70 mu m IR dark clump (MM1) that has the potential to form high-mass stars. We observed this prestellar clump candidate ...

A molecular outflow revealing star formation activity in the vicinity of the HII region G034.8-0.7 and the SNR W44

Paron, Sergio Ariel; Ortega, Martin Eduardo; Rubio, M.; Dubner, Gloria Mabel (EDP Sciences, 2009-05)

Aims. This work aims at investigating the molecular gas component in the vicinity of two young stellar object (YSO) candidates identified at the border of the HII region G034.8-0.7 that is evolving within a molecular cloud ...

The low-frequency radio emission and spectrum of the extended SNR W44: new VLA observations at 74 and 324 MHz

Castelletti, Gabriela Marta; Dubner, Gloria Mabel; Brogan, C.; Kassim, N. E. (EDP Sciences, 2007-12)

Aims. We present new Very Large Array (VLA) radio images at 74 and 324 MHz of the SNR W44. The VLA images, obtained with unprecedented angular resolution and sensitivity for such low frequencies (HPBW 37 at 74 MHz, and 13 ...

Close binary companions of the HAeBe stars LkHα 198, Elias 1, HK Ori and V380 Ori.

Smith, K. W.; Balega, Y. Y.; Lachaume, Regis; Duschl, W. J.; Hofmann, K.-H.; Preibisch, T.; Schertl, D.; Weigelt, G. (2005)

New VLA observations of the SNR Puppis A : the radio properties and the correlation with the X-ray emission

Castelletti, Gabriela Marta; Dubner, Gloria Mabel; Golap, K.; Goss, W. M. (EDP Sciences, 2006-12)

Context. High-resolution, high-sensitivity multifrequency radio images of supernova remnants (SNRs) are essential in advancing the understanding of both the global SNR dynamics and particle acceleration mechanisms. Aims. ...

The MURALES survey II. Presentation of MUSE observations of 20 3C low-z radio galaxies and first results

Balmaverde, B.; Capetti, A.; Marconi, A.; Venturi, Giacomo; Chiaberge, M.; Baldi, R.; Baum, S.; Gilli, R.; Grandi, P.; Meyer, E.; Miley, G.; O'Dea, C.; Sparks, W.; Torresi, E.; Tremblay, G. (2019)

On-sky performance of the CLASS Q-band telescope

Appel, J.W.; Xu, Z.L.; Padilla, I.L.; Harrington, K.; Marquez, B.P.; Ali, A.; Bennett, C.L.; Brewer, M.K.; Dunner Planella, Rolando; Eimer, J.R. (2019)

Molecular Line Emission Towards High-Mass Clumps: The MALT90 Catalogue

Rathborne, Jill; Whitaker, John; Jackson, J. M.; Foster, J. B.; Contreras, Y.; Stephens, I. W.; Guzmán Fernández, Andrés; Longmore, S. N.; Sanhueza, P.; Schuller, F.; Wyrowski, Friedrich; Urquhart, J. S. (Cambridge University Press, 2016)

The Millimetre Astronomy Legacy Team 90 GHz survey aims to characterise the physical and chemical evolution of high-mass clumps. Recently completed, it mapped 90 GHz line emission towards 3 246 high-mass clumps identified ...
