A Radio Continuum Study of Dwarf Galaxies : 6 cm imaging of Little Things
(2018-02-01)
In this paper, we examine to what extent the radio continuum can be used as an extinction-free probe of star formation in dwarf galaxies. To that aim, we observe 40 nearby dwarf galaxies with the Very Large Array at 6 cm ...
WISDOM Project - III. Molecular gas measurement of the supermassive black hole mass in the barred lenticular galaxy NGC4429
(2018-01-21)
As part of the mm-Wave Interferometric Survey of Dark Object Masses project we present an estimate of the mass of the supermassive black hole (SMBH) in the nearby fast-rotating early-type galaxy NGC4429, that is barred and ...
Was Proxima captured by alpha Centauri A and B?
(2018-01-21)
The nearest stellar system consists of the stars Proxima, Alpha Centauri A and B and at least one planet Proxima b. The habitability of Proxima b and any other planets are likely to be significantly influenced by the orbital ...
The New Galaxy Evolution Paradigm Revealed by the Herschel Surveys
(2018-01-21)
The Herschel Space Observatory has revealed a very different galaxyscape from that shown by optical surveys which presents a challenge for galaxy-evolution models. The Herschel surveys reveal (1) that there was rapid galaxy ...
Photometric redshifts for the next generation of deep radio continuum surveys - I. Template fitting
(2018-01-11)
We present a study of photometric redshift performance for galaxies and active galactic nuclei detected in deep radio continuum surveys. Using two multiwavelength data sets, over the NOAO Deep Wide Field Survey Boötes and ...
`Oumuamua as a messenger from the Local Association
(2018-01-09)
With a hyperbolic trajectory around the Sun, 'Oumuamua is the first confirmed interstellar object. However, its origin is poorly known. By simulating the orbits of 0.23 million local stars, we find 109 encounters with ...
ATLASGAL - properties of a complete sample of Galactic clumps
(2018-01-01)
The APEX Telescope Large Area Survey of the Galaxy (ATLASGAL) is an unbiased 870 μm submillimetre survey of the inner Galactic plane (|ℓ| < 60° with |b| < 1.°5). It is the largest and most sensitive ground-based submillimetre ...
280 one-opposition near-Earth asteroids recovered by the EURONEAR with the Isaac Newton Telescope
(2018-01-01)
Context. One-opposition near-Earth asteroids (NEAs) are growing in number, and they must be recovered to prevent loss and mismatch risk, and to improve their orbits, as they are likely to be too faint for detection in ...
RAiSE II: resolved spectral evolution in radio AGN
(2018-01-01)
The active galactic nuclei (AGN) lobe radio luminosities modelled in hydrodynamical simulations and most analytical models do not address the redistribution of the electron energies due to adiabatic expansion, synchrotron ...
Cluster richness-mass calibration with cosmic microwave background lensing
(2017-11-01)
Identifying galaxy clusters through overdensities of galaxies in photometric surveys is the oldest and arguably the most economic and mass-sensitive detection method, compared to X-ray and Sunyaev-Zel'dovich Effect surveys ...
