Gaia-assisted discovery of a detached low-ionisation BAL quasar with very large ejection velocities
J. P. U. Fynbo, P. Møller, K. E. Heintz +10
We report on the discovery of a peculiar Broad Absorption Line (BAL) quasar identified in our Gaia-assisted survey of red quasars. The systemic redshift of this quasar was difficul…
Serendipitous discovery of a physical binary quasar at z=1.76
E. Altamura, S. Brennan, A. Leśniewska +7
Binary quasars are extremely rare objects, used to investigate clustering on very small scales at different redshifts. The cases where the two quasar components are gravitationally…
Exploring galaxy dark matter halos across redshifts with strong quasar absorbers
L. Christensen, P. Møller, N. H. P. Rhodin +2
Quasar lines of sight intersect intervening galaxy discs or circum-galactic environments at random impact parameters and potential well depths. Absorption line velocity widths ($Δv…
Metallicity has followed local gravitational potential of galaxies since z=3
Palle Møller, Lise Christensen
The MZ relation between stellar mass (M*) and metallicity (Z) of nearby galaxies has been described as both a global and local property, i.e. valid also on sub-galaxy scales. Here…
A superluminous supernova in high surface density molecular gas within the bar of a metal-rich galaxy
M. Arabsalmani, S. Roychowdhury, F. Renaud +8
We report the Atacama Large Millimeter/submillimeter Array (ALMA) observations of the metal rich host galaxy of superluminous supernova (SLSN) PTF10tpz, a barred spiral galaxy at z…
Linking gas and galaxies at high redshift: MUSE surveys the environments of six damped Lyman alpha galaxies at z~3
Ruari Mackenzie, Michele Fumagalli, Tom Theuns +12
We present results from a survey of galaxies in the fields of six z>3 Damped Lyman alpha systems (DLAs) using the Multi Unit Spectroscopic Explorer (MUSE) at the Very Large Telesco…
The effect of dust bias on the census of neutral gas and metals in the high-redshift Universe due to SDSS-II quasar colour selection
Jens-Kristian Krogager, Johan P. U. Fynbo, Palle Møller +3
We present a systematic study of the impact of a dust bias on samples of damped Lyman- absorbers (DLAs). This bias arises as an effect of the magnitude and colour criteria utili…
Gaia-assisted selection of a quasar reddened by dust in an extremely-strong Damped Lyman-α Absorber at z=2.226
Stefan Geier, Kasper Elm Heintz, Johan Fynbo +7
Damped Lyman-α Absorbers (DLAs) as a class of QSO absorption-line systems are currently our most important source of detailed information on the cosmic chemical evolution of galaxi…
The host galaxy of GRB 980425 / SN1998bw: a collisional ring galaxy
M. Arabsalmani, S. Roychowdhury, T. K. Starkenburg +8
We report Giant Metrewave Radio Telescope (GMRT) , Very Large Telescope (VLT) and Spitzer Space Telescope observations of ESO 184G82, the host galaxy of GRB 980425/SN 1998bw, th…
