The Performance of Photometric Reverberation Mapping at High Redshift and the Reliability of Damped Random Walk Models
(2019-12-20)
Accurate methods for reverberation mapping using photometry are highly sought after since they are inherently less resource intensive than spectroscopic techniques. However, the effectiveness of photometric reverberation ...
Comparing simulated $^{26}$Al maps to gamma-ray measurements
(2019-12-03)
Context. The diffuse gamma-ray emission of $^{26}{\rm Al}$ at 1.8 MeV reflects ongoing nucleosynthesis in the Milky Way, and traces massive-star feedback in the interstellar medium due to its 1 Myr radioactive lifetime. ...
ATLASGAL -- physical parameters of dust clumps associated with 6.7 GHz methanol masers
(2019-12-01)
We have constructed the largest sample of dust-associated class II 6.7 GHz methanol masers yet obtained. New measurements from the the Methanol MultiBeam (MMB) Survey were combined with the 870 $\mu$m APEX Telescope Large ...
CHIMPS: Physical properties of molecular clumps across the inner Galaxy
(2019-12-01)
The latest generation of high-angular-resolution unbiased Galactic plane surveys in molecular-gas tracers are enabling the interiors of molecular clouds to be studied across a range of environments. The CHIMPS survey ...
Multi-wavelength properties of radio and machine-learning identified counterparts to submillimeter sources in S2COSMOS
(2019-11-20)
We identify multi-wavelength counterparts to 1,147 submillimeter sources from the S2COSMOS SCUBA-2 survey of the COSMOS field by employing a recently developed radio$+$machine-learning method trained on a large sample of ...
The Milky Way bar/bulge in proper motions: a 3D view from VIRAC & Gaia
(2019-11)
We have derived absolute proper motions of the entire Galactic bulge region from VIRAC and Gaia. We present these as both integrated on-sky maps and, after isolating standard candle red clump (RC) stars, as a function of ...
JINGLE V : Dust properties of nearby galaxies derived from hierarchical Bayesian SED fitting
(2019-11-01)
We study the dust properties of 192 nearby galaxies from the JINGLE survey using photometric data in the 22-850 μm range. We derive the total dust mass, temperature T, and emissivity index β of the galaxies through the ...
A LOFAR-IRAS cross-match study : the far-infrared radio correlation and the 150-MHz luminosity as a star-formation rate
(2019-11-01)
Aims. We aim to study the far-infrared radio correlation (FIRC) at 150 MHz in the local Universe (at a median redshift z~0:05) and improve the use of the rest-frame 150-MHz luminosity, L150, as a star-formation rate (SFR) ...
Galaxy morphological classification in deep-wide surveys via unsupervised machine learning
(2019-10-26)
Galaxy morphology is a fundamental quantity, that is essential not only for the full spectrum of galaxy-evolution studies, but also for a plethora of science in observational cosmology. While a rich literature exists on ...
VLA cm-wave survey of young stellar objects in the Oph A cluster : constraining extreme UV- and X-ray-driven disk photo-evaporation -- A pathfinder for Square Kilometre Array studies
(2019-10-21)
Observations of young stellar objects (YSOs) in centimeter bands can probe the continuum emission from growing dust grains, ionized winds, and magnetospheric activity, which are intimately connected to the evolution of ...
