Cold gas in the early Universe. Survey for neutral atomic-carbon in GRB host galaxies at 1 < z < 6 from optical afterglow spectroscopy
K. E. Heintz, C. Ledoux, J. P. U. Fynbo +14
We present a survey for neutral atomic-carbon (CI) along gamma-ray burst (GRB) sightlines, which probes the shielded neutral gas-phase in the interstellar medium (ISM) of GRB host…
Metals, depletion and dimming: decrypting dust
Tayyaba Zafar, Palle Møller
Dust plays a pivotal role in the chemical enrichment of the interstellar medium. In the era of mid/high resolution spectra and multi-band spectral energy distributions, testing ext…
Evidence for diffuse molecular gas and dust in the hearts of gamma-ray burst host galaxies
J. Bolmer, C. Ledoux, P. Wiseman +17
Here we built up a sample of 22 GRBs at redshifts observed with X-shooter to determine the abundances of hydrogen, metals, dust, and molecular species. This allows us to st…
The luminous host galaxy, faint supernova and rapid afterglow rebrightening of GRB 100418A
A. de Ugarte Postigo, C. C. Thoene, K. Bensch +35
Long gamma-ray bursts give us the chance to study both their extreme physics and the star-forming galaxies in which they form. GRB 100418A, at a z = 0.6239, had a bright optical an…
X-shooting GRBs at high redshift: probing dust production history
T. Zafar, P. Møller, D. Watson +16
Evolved asymptotic giant branch (AGB) stars and Type Ia supernovae (SNe) are important contributors to the elements that form dust in the interstellar medium of galaxies, in partic…
DLA and sub-DLA metallicity evolution: A case study of absorbers towards Q0338-0005
Waqas Bashir, Tayyaba Zafar, Fazeel M. Khan +1
The damped and sub-damped Lyman alpha systems (DLAs and sub-DLAs) traced in absorption against bright background quasars represent the main reserve of neutral hydrogen at high reds…
Stellar masses, metallicity gradients and suppressed star formation revealed in a new sample of absorption selected galaxies
N. H. P. Rhodin, L. Christensen, P. Møller +2
Context. Absorbing galaxies are selected via the detection of characteristic absorption lines which their gas-rich media imprint in the spectra of distant light-beacons. The proxim…
The SAMI Galaxy Survey: Spatially Resolved Metallicity and Ionization Mapping
Henry Poetrodjojo, Brent Groves, Lisa J. Kewley +16
We present gas-phase metallicity and ionization parameter maps of 25 star-forming face-on spiral galaxies from the SAMI Galaxy Survey Data Release 1. Self-consistent metallicity an…
Investigation of dust attenuation and star formation activity in galaxies hosting GRBs
D. Corre, V. Buat, S. Basa +6
The gamma-ray bursts hosts (GRBHs) are excellent targets to study the extinction properties of dust and its effects on the global emission of distant galaxies. The dust extinction…
The 2175 Å extinction feature in the optical afterglow spectrum of GRB 180325A at z=2.25
T. Zafar, K. E. Heintz, J. P. U. Fynbo +26
The UV extinction feature at 2175 Å is ubiquitously observed in the Galaxy but is rarely detected at high redshifts. Here we report the spectroscopic detection of the 2175 Å bump o…
X-shooter and ALMA spectroscopy of GRB 161023A - A study of metals and molecules in the line of sight towards a luminous GRB
A. de Ugarte Postigo, C. C. Thöne, J. Bolmer +45
Long gamma-ray bursts are produced during the dramatic deaths of massive stars with very short lifetimes, meaning that they explode close to the birth place of their progenitors. D…
VLT/X-shooter GRBs: Individual extinction curves of star-forming regions
T. Zafar, D. Watson, P. Møller +14
The extinction profiles in Gamma-Ray Burst (GRB) afterglow spectral energy distributions (SEDs) are usually described by the Small Magellanic Cloud (SMC)-type extinction curve. In…
The SAMI Galaxy Survey: Spatially Resolving the Main Sequence of Star Formation
Anne M. Medling, Luca Cortese, Scott M. Croom +42
We present the ~800 star formation rate maps for the SAMI Galaxy Survey based on Hα emission maps, corrected for dust attenuation via the Balmer decrement, that are included in the…
