MUSE-AO view of the starburst-AGN connection: NGC 7130
We present the discovery of a small kinematically decoupled core of 0.″2 (60 pc) in radius as well as an outflow jet in the archetypical AGN-starburst...
MUSEQuBES: calibrating the redshifts of Ly α emitters using stacked circumgalactic medium absorption profiles
Ly α emission lines are typically found to be redshifted with respect to the systemic redshifts of galaxies, likely due to resonant scattering of Ly α photons...
MuSICa: The Multi-Slit Image Slicer for the EST Spectrograph
Integral field spectroscopy (IFS) is a technique that allows one to obtain the spectra of all the points of a bidimensional field of view simultaneously. It is...
MUSSES2020J: The Earliest Discovery of a Fast Blue Ultraluminous Transient at Redshift 1.063
In this Letter, we report the discovery of an ultraluminous fast-evolving transient in rest-frame UV wavelengths, MUSSES2020J, soon after its occurrence by...
MY Camelopardalis, a very massive merger progenitor
Context. The early-type binary MY Cam belongs to the young open cluster Alicante 1, embedded in Cam OB3. Aims: MY Cam consists of two early-O type main-sequence...
Na I and Hα absorption features in the atmosphere of MASCARA-2b/KELT-20b
We used the HARPS-North high resolution spectrograph (ℛ = 115 000) at Telescopio Nazionale Galileo (TNG) to observe one transit of the highly irradiated planet...
Naked emergence of an anti-Hale active region. I. Overall evolution and magnetic properties
Aims: In order to understand the emergence of the active region, we investigate the emerging process and magnetic properties of a naked anti-Hale active region...
Nanodiamond Dust and the Far-Ultraviolet Quasar Break
We explore the possibility that the steepening observed shortward of 1000 Å in the energy distribution of quasars may result from absorption by dust, being...
