A FPGA-based Fast Converging Digital Adaptive Filter for Real-time RFI Mitigation on Ground Based Radio Telescopes
R. Finger, F. Curotto, R. Fuentes +3
Radio Frequency Interference (RFI) is a growing concern in the radio astronomy community. Single-dish telescopes are particularly susceptible to RFI. Several methods have been deve…
SEDIGISM: Structure, excitation, and dynamics of the inner Galactic interstellar medium
F. Schuller, T. Csengeri, J. S. Urquhart +41
The origin and life-cycle of molecular clouds are still poorly constrained, despite their importance for understanding the evolution of the interstellar medium. We have carried out…
Physical characterization of S169: A prototypical IR bubble associated with the massive star-forming region IRAS12326-6245
N. U. Duronea, S. Cichowolski, L. Bronfman +5
With the aim of studying the properties of Galactic IR bubbles and their impact in massive star formation, we present a study of the IR bubble S169, associated with the massive sta…
Digital compensation of the side-band-rejection ratio in a fully analog 2SB sub-millimeter receiver
R. Rodriguez, R. Finger, F. P. Mena +7
In observational radio astronomy, sideband-separating receivers are preferred, particularly under high atmospheric noise, which is usually the case in the sub-millimeter range. How…
SiO Outflows in the Most Luminous and Massive Protostellar Sources of the Southern Sky
N. Guerra-Varas, M. Merello, L. Bronfman +4
(Abridged) High-mass star formation is far less understood than low-mass star formation. It entails molecular outflows, which disturb the protostellar clump. Studying these outflow…
G331.512-0.103: An Interstellar Laboratory for Molecular Synthesis I. The Ortho-to-para Ratios for CHOH and CHCN
E. Mendoza, L. Bronfman, N. U. Duronea +7
Spectral line surveys reveal rich molecular reservoirs in G331.512-0.103, a compact radio source in the center of an energetic molecular outflow. In this first work, we analyse the…
