THE STRUCTURE OF NGC 1976 IN THE RADIO RANGE
(2012-01-10)
High angular resolution radio continuum images of NGC 1976 (M42, Orion A) at ν = 330 MHz (λ = 91 cm),
1.5 GHz (20 cm), and 10.6 GHz (2.8 cm) have been aligned, placed on a common grid, smoothed to common
resolutions of ...
Procesos interactivos mediáticos de Radio Sutatenza con los campesinos de Colombia
(2011-01)
A partir de los procesos interactivos mediáticos de Radio Sutatenza con los campesinos, la investigación muestra cómo esta experiencia contribuyó al cambio social, al desarrollo, desde el conocimiento de su realidad ...
An updated 2017 astrometric solution for betelgeuse
(IOP Publishing, 2017)
We provide an update for the astrometric solution for the Type II supernova progenitor Betelgeuse using the revised Hipparcos Intermediate Astrometric Data (HIAD) of van Leeuwen, combined with existing VLA and new e-MERLIN ...
Joint Power, Original Bandwidth, and Detected Hole Bandwidth Allocation for Multi-Homing Heterogeneous Networks Based on Cognitive Radio
(Institute of Electrical and Electronics Engineers Inc., 2019)
In this paper, we investigate a joint resource allocation problem based on cognitive radio (CR) techniques for user equipment with multi-homing capabilities. We consider a heterogeneous wireless medium where users in ...
CCD astrometry of faint compact extragalactic radio sources. II.
(2001)
Optical positions relative to the Hipparcos Catalogue (ESA 1997) have been obtained for the optical
counterparts of 28 faint (B 20−23) southern compact extragalactic radio sources (CERS). Most of these sources
are not ...
Cepheus A HW2: A powerful thermal radio jet
(UNIV CHICAGO PRESS, 1994-07-20)
At angular resolution of approximately 1 arc second(s) the Cepheus A East Radio source is known to consist of 16 compact components clustered within a 25 arc second(s) radius region, most of which are aligned in stringlike ...
A FPGA-based fast converging digital adaptive filter for real time RFI mitigation on ground based radio telescopes
(IOP Publishing Ltd, 2018)
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 developed to cope with RF-polluted environments, ...
A parsec-scale flow associated with the IRAS 16547-4247 radio jet
(UNIV CHICAGO PRESS, 2003-09-10)
IRAS 16547 - 4247 is the most luminous (6.2 x 10(4) L-.) embedded young stellar object known to harbor a thermal radio jet. We report the discovery using the Very Large Telescope Infrared Spectrometer and Array Camera of ...
