The atomic gas of star-forming galaxies at z similar to 0.05 as revealed by the Five-hundred-meter Aperture Spherical Radio Telescope
(EDP Science, 2020)
Context. We report new HI observations of four z similar to 0.05 VALES galaxies undertaken during the commissioning phase of the Five-hundred-meter Aperture Spherical Radio Telescope (FAST).Aims. FAST is the largest ...
A Photoionized Accretion Disk around a Young High-mass Star
(IOP, 2020)
We present high spatial resolution (52 au) observations of the high-mass young stellar object (HMYSO) G345.4938+01.4677 made using the Atacama Large Millimeter/submillimeter Array. This O-type HMYSO is located at 2.38 kpc ...
An H2Co 6 cm maser pinpointing a possible circumstellar torus in IRAS 18566+0408
(UNIV CHICAGO PRESS, 2007-11-10)
We report observations of 6 cm, 3.6 cm, 1.3 cm, and 7 mm radio continuum, conducted with the Very Large Array, toward IRAS 18566+0408, one of the few sources known to harbor H(2)CO6 cm maser emission. Our observations ...
Field emission properties of carbon nanowalls prepared by RF magnetron sputtering
(Springer Verlag, 2019)
Carbon nanowalls were prepared on silicon substrates by radio frequency magnetron sputtering under an argon–hydrogen mixture, at different hydrogen fluxes and varying the substrate temperature and deposition times. Scanning ...
Control of deviations and prediction of surface roughness from micro machining of THz waveguides using acoustic emission signals
(Academic Press-Elsevier, 2017)
By using acoustic emission (AE) it is possible to control deviations and surface quality during micro milling operations. The method of micro milling is used to manufacture a submillimetre waveguide where micro machining ...
AGN feedback in the nucleus of M51
(EDP Sciences, 2016)
AGN feedback is invoked as one of the most relevant mechanisms that shape the evolution of galaxies. Our goal is to understand the interplay between AGN feedback and the interstellar medium in M 51, a nearby spiral galaxy ...
Multiwavelength variability power spectrum analysis of the blazars 3C 279 and PKS 1510–089 on multiple timescales
(IOP, 2022)
We present the results of variability power spectral density (PSD) analysis using multiwavelength radio to GeV gamma-ray light curves covering timescales of decades/years to days/minutes for the blazars 3C 279 and PKS ...
Multiwavelength study of the nuclei of a volume-limited sample of galaxies - II. Optical, infrared and radio observations
(2007-12-21)
We present optical and infrared broad-band images, radio maps, and optical spectroscopy for the nuclear region of a sample of nearby galaxies. The galaxies have been drawn from a complete volume-limited sample for which ...
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 ...
A glance at the host galaxy of high-redshift quasars using strong damped Lyman-α systems as coronagraphs
(EDP Sciences, 2013)
We searched quasar spectra from the SDSS-III Baryon Oscillation Spectroscopic Survey (BOSS) for the rare occurrences where a
strong damped Lyman-α absorber (DLA) blocks the Broad Line Region emission from the quasar and ...
