We present a detailed analysis of the absorption properties of one of the tidal gas streams around the “Whale” galaxy NGC 4631 in the direction of the quasar 2MASS J12421031+3214268. Our study is based on ultraviolet spectral data obtained…

Obscured flat spectrum radio active galactic nuclei as sources of high-energy neutrinos Open

G. Maggi, S. Buitink, Pablo Correa, K. D. de Vries, G. Gentile , et al. · 2016

Active Galactic Nuclei (AGN) are believed to be one of the main source candidates for the high-energy (TeV-PeV) cosmic neutrino flux recently discovered by the IceCube neutrino observatory. Nevertheless, several correlation studies between…

The<i>Herschel</i>Exploitation of Local Galaxy Andromeda (HELGA) Open

S. Viaene, M. Baes, A. Tamm, Elmo Tempel, G. J. Bendo , et al. · 2016

The radiation from stars heats dust grains in the diffuse interstellar medium and in star-forming regions in galaxies. Modelling this interaction provides information on dust in galaxies, a vital ingredient for their evolution. It is not s…

GRB 980425 host: [C II], [O I], and CO lines reveal recent enhancement of star formation due to atomic gas inflow Open

M. J. Michałowski, J. M. Castro Cerón, J. L. Wardlow, A. Karska, Hugo Messias , et al. · 2016

\n Context. Accretion of gas from the intergalactic medium is required to fuel star formation in galaxies. We have recently suggested that this process can be studied using host galaxies of gamma-ray bursts (GRBs).\n Aims. Our aim is to te…

The Herschel Exploitation of Local Galaxy Andromeda (HELGA) VII: A SKIRT radiative transfer model and insights on dust heating Open

S. Viaene, M. Baes, A. Tamm, Elmo Tempel, G. J. Bendo , et al. · 2016

The radiation of stars heats dust grains in the diffuse interstellar medium and in star-forming regions in galaxies. Modelling this interaction provides information on dust in galaxies, a vital ingredient for their evolution. It is not str…

Dynamical measurement of the stellar surface density of face-on galaxies Open

G. W. Angus, G. Gentile, Benoît Famaey · 2015

\n The DiskMass survey recently provided measurements of the vertical velocity dispersions of disk stars in a sample of nearly face-on galaxies. By setting the disk scale-heights to be equal to those of edge-on galaxies with similar scale-…

Search for high-energy neutrinos from dust obscured Blazars Open

G. Maggi, S. Buitink, Pablo Correa, K. D. de Vries, G. Gentile , et al. · 2015

The recent discovery of high-energy cosmic neutrinos by the IceCube neutrino observatory opens up a new field in physics, the field of neutrino astronomy. Using the IceCube neutrino detector we plan to search for high-energy neutrinos emit…

Massive stars formed in atomic hydrogen reservoirs: H I observations of gamma-ray burst host galaxies Open

M. J. Michałowski, G. Gentile, J. Hjorth, Mark R. Krumholz, N. R. Tanvir , et al. · 2015

Long gamma-ray bursts (GRBs), among the most energetic events in the Universe, are explosions of massive and short-lived stars, so they pinpoint locations of recent star formation. However, several GRB host galaxies have recently been foun…

<i>HERschel</i>Observations of Edge-on Spirals (HEROES) Open

F. Allaert, G. Gentile, M. Baes, Gert De Geyter, T. M. Hughes , et al. · 2015
