LS 5039: A runaway microquasar ejected from the galactic plane
(EDP Sciences, 2002-03)
We have compiled optical and radio astrometric data of the microquasar LS 5039 and derived its proper motion. This, together with the distance and radial velocity of the system, allows us to state that this source is ...
SEDIGISM: Structure, excitation, and dynamics of the inner Galactic interstellar medium
(EDP Sciences, 2017-05)
Context. The origin and life-cycle of molecular clouds are still poorly constrained, despite their importance for understanding the evolution of the interstellar medium. Many large-scale surveys of the Galactic plane have ...
A hadronic scenario for HESS J1818-154
(Edp Sciences, 2013-09)
Aims: G15.4+0.1 is a faint supernova remnant (SNR) that has recently been associated with the γ-ray source HESS J1818-154. We investigate a hadronic scenario for the production of the γ-ray emission. Methods: Molecular ...
The ISM around WR Stars: WR152 and WR153ab
(Astronomical Society Of The Pacific, 2008-12)
We analyze the distribution of interstellar matter in the environs of the WR stars WR 152 and WR 153ab, associated with two different ring nebulae in the H ii region Sh2-132. We have detected the radio continuum and infrared ...
A CGPS view of the ISM towards HD 192281
(Astronomical Society of the Pacific, 2010-12)
Massive stars are known to have a profound impact on their surroundings through their high ionizing radiation, their strong stellar winds, and their eventual final explosion as supernovae. Within the area surveyed by ...
Unveiling the circumstellar environment toward a massive young stellar object
(Edp Sciences, 2013-11)
Aims: As a continuation of a previous work, in which we found strong evidence of massive molecular outflows toward a massive star-forming site, we present a new study of this region based on very high angular resolution ...
Spectral imaging of the Sagittarius B2 region in multiple 7-mm molecular lines
(WILEY-BLACKWELL, 2011-03)
We have undertaken a spectral-line imaging survey of a 6 x 6 arcmin2 area around Sagittarius (Sgr) B2 near the centre of the Galaxy, in the range from 30 to 50 GHz, using the Mopra telescope. The spatial resolution varies ...
El medio interestelar en los alrededores de la region HII Sh2-183
(Asociación Argentina de Astronomía, 2017-10)
We present a multiwavelength study of the HII region Sh2-183, located at(,) = (123.3,+3.0) at a distance of 7.0 1.5 kpc from the Sun. Based onthe radio continuum data we estimated the amount of ionized gas, theelectronic ...
Simulated synchrotron emission for the Tycho's supernova remnants: An asymmetric initial mass model
(Wiley Blackwell Publishing, Inc, 2020-05)
We have performed 3D magnetohydrodynamics (MHD) numerical simulations with the aim of exploring the scenario in which the initial mass distribution of a supernova (SN) explosion is anisotropic. The purpose is to analyse ...
