The central energy source of 70 μm-selected galaxies: starburst or AGN? [PDF]
, 2009 We present the first active galactic nuclei (AGN) census in a sample of 61 galaxies selected at 70 mu m, a wavelength which should strongly favour the detection of star-forming systems.

Cosmic ray transport in starburst galaxies [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Starburst galaxies are efficient γ-ray producers, because their high supernova rates generate copious cosmic ray (CR) protons, and their high gas densities act as thick targets off which these protons can produce neutral pions and thence γ-rays.

Extreme submillimetre starburst galaxies [PDF]
Astronomy & Astrophysics, 2018 We have used two catalogues, a Herschel catalogue selected at 500 μm (HerMES) and an IRAS catalogue selected at 60 μm (RIFSCz), to contrast the sky at these two wavelengths. Both surveys demonstrate the existence of “extreme” starbursts, with star-formation rates (SFRs) > 5000 M⊙ yr−1.

Densitometry and Thermometry of Starburst Galaxies [PDF]
EAS Publications Series, 2011 With a goal toward deriving the physical conditions in external galaxies, we present a survey of formaldehyde (H2CO) and ammonia (NH3) emission and absorption in a sample of starburst galaxies using the Green Bank Telescope. By extending well-established techniques used to derive the spatial density in star formation regions in our own Galaxy, we show ...

The Colors and Sizes of Recently Quenched Galaxies: A Result of Compact Starburst before Quenching [PDF]
Astrophysical Journal, 2019 We analyze the colors and sizes of 32 quiescent (UVJ-selected) galaxies with strong Balmer absorption (EW(Hδ) ≥ 4 Å) at z ∼ 0.8 drawn from DR2 of the LEGA-C survey to test the hypothesis that these galaxies experienced compact, central starbursts before ...

Post-starburst galaxies in SDSS-IV MaNGA [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Post-starburst galaxies, identified by their unusually strong Balmer absorption lines and weaker than average emission lines, have traditionally been selected based on their central stellar populations. Here we identify 360 galaxies with post-starburst

Cosmic ray transport and radiative processes in nuclei of starburst galaxies [PDF]
Monthly notices of the Royal Astronomical Society, 2018 The high rate of star formation and supernova explosions of starburst galaxies make them interesting sources of high-energy radiation. Depending on the level of turbulence present in their interstellar medium, the bulk of cosmic rays produced inside ...

Clocking the Evolution of Post-starburst Galaxies: Methods and First Results [PDF]
Astrophysical Journal, 2018 Detailed modeling of the recent star formation histories (SFHs) of post-starburst (or “E+A”) galaxies is impeded by the degeneracy between the time elapsed since the starburst ended (post-burst age), the fraction of stellar mass produced in the burst ...

Evolution of the cold gas properties of simulated post-starburst galaxies [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Post-starburst galaxies are typically considered to be a transition population, en route to the red sequence after a recent quenching event. Despite this, recent observations have shown that these objects typically have large reservoirs of cold molecular
