The large and small scale properties of the intergalactic gas in the Slug Ly-alpha nebula revealed by MUSE HeII emission observations
Sebastiano Cantalupo, Gabriele Pezzulli, Simon J. Lilly +11
With a projected size of about 450 kpc at z~2.3, the Slug Ly-alpha nebula is a rare laboratory to study, in emission, the properties of the intergalactic gas in the Cosmic Web. Sin…
Galaxy and Quasar Fueling Caught in the Act from the Intragroup to the Interstellar Medium
Sean D. Johnson, Hsiao-Wen Chen, Lorrie A. Straka +11
We report the discovery of six spatially extended (10-100 kpc) line-emitting nebulae in the z=0.57 galaxy group hosting PKS0405-123, one of the most luminous quasars at z<1. The di…
MUSE Spectroscopic Identifications of Ultra-Faint Emission Line Galaxies with M -15
Michael V. Maseda, Roland Bacon, Marijn Franx +16
Using an ultra-deep blind survey with the MUSE integral field spectrograph on the ESO Very Large Telescope, we obtain spectroscopic redshifts to a depth never explored before: gala…
QSO MUSEUM I: A sample of 61 extended Ly-emission nebulae surrounding quasars
F. Arrigoni Battaia, J. F. Hennawi, J. X. Prochaska +4
Motivated by the recent discovery of rare Enormous Lyman-Alpha Nebulae (ELAN) around z~2 quasars, we have initiated a long-term observational campaign with the MUSE instrument to d…
MCMC determination of the cosmic UV background at from H fluorescence
Davide Caruso, Francesco Haardt, Michele Fumagalli +1
In a recent paper (Fumagalli et al. 2017) we reported on the detection of a diffuse H glow in the outskirts of the nearby, edge-on disc galaxy UGC 7321 observed with the Multi U…
Properties and redshift evolution of star-forming galaxies with high [OIII]/[OII] ratios with MUSE at 0.28<z<0.85
M. Paalvast, A. Verhamme, L. A. Straka +21
We present a study of the [OIII]5007/[OII]3727 (O32) ratios of star-forming galaxies drawn from MUSE data spanning a redshift range 0.28<z<0.85. Recently discovered Lyman continuum…
