We have observed the host galaxy of the low redshift, low luminosity GRB 080517 at 105.8 GHz using the IRAM Plateau de Bure interferometer. We detect an emission line with integrated flux S.delta{nu} = 0.39 +/- 0.05 Jy km/s - consistent both spatially and in velocity with identification as the J=1-0 rotational transition of carbon monoxide (CO) at the host galaxy redshift. This represents only the third long GRB host galaxy with molecular gas detected in emission. The inferred molecular gas mass, M_H2 ~ 6.3 x 10^8 M_sun, implies a gas consumption timescale of ~40 Myr if star formation continues at its current rate. Similar short timescales appear characteristic of the long GRB population with CO observations to date, suggesting that the gamma-ray burst in these sources occurs towards the end of their star formation episode.

  1. The ALMA carbon monoxide supernova (ACOS) survey II. Turbulent giant molecular clouds at the positions of core-collapse supernovae

    astro-ph.GA 2026-08 conditional novelty 6.0 of 10

    Core-collapse supernovae are found in molecular gas with median CO(2-1) velocity dispersion of about 9 km/s, versus 3.8 km/s for typical host-galaxy pixels.

  2. Gamma-ray burst progenitors revisited

    astro-ph.HE 2026-07 conditional novelty 6.0 of 10

    About 30–40% of long gamma-ray bursts at z<0.3 lack supernova emission and likely arise from compact object mergers, at rates comparable to short GRBs.

  3. Mass--size evolution and the emerging passive--density relation revealed by JWST/NIRCam in the Spiderweb protocluster

    astro-ph.GA 2026-07 conditional novelty 6.0 of 10

    In the Spiderweb protocluster, passive fraction rises with local density to ~60% while passive mass–size intercepts sit between field and cluster values, indicating advanced quenching but ongoing size growth.
