Non-thermal radio emission from OB stars: an observer’s view
(Astromical Society of the Pacific, 2010-05)
Some early-type stars are detectable radio emitters; their spectra can present both thermal and non-thermal contributions. Here I review the public radio data on OB stars, focusing on the non-thermal sources. The analysis ...
Relativistic plasma as the dominant source of the optical continuum emission in the broad-line radio galaxy 3C 120
(The Astrophysical Journal, 2010)
Cosmic evolution of molecular gas mass density from an empirical relationship between L1.4 GHz and L′CO
(Royal Astronomical Society, 2020)
Historically, GHz radio emission has been used extensively to characterize the star-formation activity in galaxies. In this work, we look for empirical relationships amongst the radio luminosity, the infrared luminosity, ...
Nonthermal emission and particle acceleration in protostellar jets
(Publications of the Astronomical Society of the Pacific, 2018-11)
The presence of non thermal emission detected at radio frequencies in some protostellar jets, constitutes a remarkable discovery with very imporant implications: (1) these low energy systems should be able to accelerate ...
Mechanism for fast radio bursts
(American Physical Society, 2016-01)
Fast radio bursts are mysterious transient sources likely located at cosmological distances. The derived brightness temperatures exceed by many orders of magnitude the self-absorption limit of incoherent synchrotron ...
