Context. This study is aimed at identifying possible low-mass and sub-stellar companions to stars with well-determined metallicities. We investigate the...
The wide-field, multiplexed, spectroscopic facility WEAVE: Survey design, overview, and simulated implementation
WEAVE, the new wide-field, massively multiplexed spectroscopic survey facility for the William Herschel Telescope, saw first light in late 2022. WEAVE comprises...
The widest broadband transmission spectrum (0.38-1.71 μm) of HD 189733b from ground-based chromatic Rossiter-McLaughlin observations
Multiband photometric transit observations (spectro-photometric) have been used mostly so far to retrieve broadband transmission spectra of transiting...
The wind momentum-luminosity relationship of galactic A- and B-supergiants
The Balmer lines of four A Ia-supergiants (spectral type A0 to A3) and fourteen B Ia and Ib-supergiants (spectral type B0 to B3) in the solar neighbourhood are...
The WIRCam Ultra Deep Survey (WUDS). I. Survey overview and UV luminosity functions at z ˜ 5 and z ˜ 6
The aim of this paper is to introduce the WIRCam Ultra Deep Survey (WUDS), a near-IR photometric survey carried out at the CFH Telescope in the field of the...
The Wolf-Rayet star population in the dwarf galaxy NGC 625
Context. Quantifying the number, type, and distribution of Wolf-Rayet (W-R) stars is a key component in the context of galaxy evolution, since they put...
The X-ray binary X2127+119 in M15: evidence for a very low mass, stripped-giant companion
We present integral field spectroscopy of X2127+119, the luminous X-ray binary in the globular cluster M15, obtained with INTEGRAL/WYFFOS on the William...
The X-ray counterpart to the gravitational-wave event GW170817
A long-standing paradigm in astrophysics is that collisions—or mergers—of two neutron stars form highly relativistic and collimated outflows (jets) that power γ...
The X-Ray Properties of the Black Hole Transient MAXI J1659-152 in Quiescence
We present new Chandra X-ray observations of the transient black hole X-ray binary MAXI J1659-152 in quiescence. These observations were made more than one year...
