“…In the case of the host of the short burst GRB 071227 they revealed its star-bursting nature (Nicuesa Guelbenzu et al 2014), in the case discussed here they could indicate a second host-galaxy candidate. Obviously, radio data helps to gain a more complete view of the nature of the galaxies that hosted short GRBs.…”

“…Among the ensemble of about 30 identified and wellstudied hosts of short bursts (for a review, see Berger 2014), less than 1/3 are elliptical galaxies. All others show signs of starforming activity, and at least three of these are even starburst galaxies with star formation rates of the order of 100 M yr −1 (Perley et al 2012;Berger et al 2013;Nicuesa Guelbenzu et al 2014).…”

We report on the results of a comprehensive observing campaign to reveal the host galaxy of the short GRB 100628A. This burst was followed by a faint X-ray afterglow but no optical counterpart was discovered. However, inside the X-ray error circle a potential host galaxy at a redshift of z = 0.102 was soon reported in the literature. If this system is the host, then GRB 100628A was the cosmologically most nearby unambiguous short burst with a measured redshift so far. We used the multi-colour imager GROND at the ESO/La Silla MPG 2.2 m telescope, ESO/VLT spectroscopy, and deep Australia Telescope Compact Array (ATCA) radiocontinuum observations together with publicly available Gemini imaging data to study the putative host and the galaxies in the field of GRB 100628A. We confirm that inside the X-ray error circle the most probable host-galaxy candidate is the morphologically disturbed, interacting galaxy system at z = 0.102. The interacting galaxies are connected by a several kpc long tidal stream, which our VLT/FORS2 spectroscopy reveals strong emission lines of [O ii], [O iii], Hα and Hβ, characteristic for the class of extreme emissionline galaxies and indicative of ongoing star formation. The latter leaves open the possibility that the GRB progenitor was a member of a young stellar population. However, we indentify a second host-galaxy candidate slightly outside the X-ray error circle. It is a radiobright, luminous elliptical galaxy at a redshift z = 0.311. With a K-band luminosity of 2 × 10 11 L this galaxy resembles the probable giant elliptical host of the first well-localized short burst, GRB 050509B. If this is the host, then the progenitor of GRB 100628A was a member of an old stellar population.

“…Radio studies of GRB hosts have enjoyed a resurgence in the past five years (Hatsukade et al 2012;Perley et al 2015;Berger et al 2013;Stanway et al 2014;Nicuesa Guelbenzu et al 2014;Greiner et al 2016) thanks to the VLA's improved capabilities and similar improvements to other arrays, and while upper limits remain the norm a number of new detections have been reported. Already, it has become apparent that a few host candidates reported after a delay of only ∼1 year were actually long-lived afterglow emission (e.g., GRB 100621A; Greiner et al 2016).…”

We present new Jansky Very Large Array observations of five pre-Swift gamma-ray bursts for which an ultraluminous (SFR > 100 M ⊙ yr −1 ) dusty host galaxy had previously been inferred from radio or submillimetre observations taken within a few years after the burst. In four of the five cases we no longer detect any source at the host location to limits much fainter than the original observations, ruling out the existence of an ultraluminous galaxy hosting any of these GRBs. We continue to detect a source at the position of GRB 980703, but it is much fainter than it was a decade ago and the inferred radio star-formation rate (∼ 80M ⊙ ) is relatively modest. The radio flattening at 200-1000 days observed in the light curve of this GRB may have been caused by a decelerating counterjet oriented 180 degrees away from the viewer, although an unjetted wind model can also explain the data. Our results eliminate all well-established pre-Swift ULIRG hosts, and all cases for which an unobscured GRB was found in a galaxy dominated by heavily-obscured star-formation. When GRBs do occur in ULIRGs the afterglow is almost always observed to be heavily obscured, consistent with the large dust opacities and high dust covering fractions characteristic of these systems.

“…Due to a similar shape of all standard extinction and attenuation curves between 0.275 μm and V-band, our A V estimate would only be ∼10% higher if we used the LMC or the Milky Way extinction curves (Gordon et al 2003), and ∼20% higher with the Calzetti et al (2000) attenuation curve. Up to date 89 long-GRB hosts have been targeted in the radio continuum (Berger et al 2001Vreeswijk et al 2001;Fox et al 2003;Frail et al 2003;van der Horst et al 2005;Wiersema et al 2008;Michałowski et al 2009Michałowski et al , 2012bStanway et al 2010Stanway et al , 2014Watson et al 2011;Perley et al 2015b), and only 15 (∼17%) were detected: the hosts of GRB 980425 (Michałowski et al 2009), 980703 (Berger et al 2001), 000418, 010222, , 021211 (Michałowski et al 2012b), 031203 (Stanway et al 2010;Watson et al 2011;Michałowski et al 2012b), 051022, 080207, and 090404 ; 051006, 060814, 061121, 070306, (Perley et al 2015b), 080517 (Stanway et al 2015a), 100621A (Stanway et al 2014); with the addition of the hosts of short (duration <2 s) GRBs 071227 (Nicuesa Guelbenzu et al 2014), and 120804A (Berger et al 2013).

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

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 found to be deficient in molecular gas (H 2 ), believed to be the fuel of star formation. Moreover, optical spectroscopy of GRB afterglows implies that the molecular phase constitutes only a small fraction of the gas along the GRB line of sight. Here we report the first ever 21 cm line observations of GRB host galaxies, using the Australia Telescope Compact Array, implying high levels of atomic hydrogen (H i), which suggests that the connection between atomic gas and star formation is stronger than previously thought. In this case, it is possible that star formation is directly fuelled by atomic gas (or that the H i-to-H 2 conversion is very efficient, which rapidly exhaust molecular gas), as has been theoretically shown to be possible. This can happen in low-metallicity gas near the onset of star formation because cooling of gas (necessary for star formation) is faster than the H i-to-H 2 conversion. Indeed, large atomic gas reservoirs, together with low molecular gas masses, stellar, and dust masses are consistent with GRB hosts being preferentially galaxies which have very recently started a star formation episode after accreting metal-poor gas from the intergalactic medium. This provides a natural route for forming GRBs in low-metallicity environments. The gas inflow scenario is also consistent with the existence of the companion H i object with no optical counterpart ∼19 kpc from the GRB 060505 host, and with the fact that the H i centroids of the GRB 980425 and 060505 hosts do not coincide with optical centres of these galaxies, but are located close to the GRB positions.
