The black hole transient MAXI J1820+070 displayed optical P Cyg profiles and other wind-related emission line features during the hard state of its discovery...

We present the results of a high resolution (0.27'' px(-1) ) near-infrared H band (1.65 μm) imaging survey of a complete sample of 20 flat spectrum radio...

We present near-infrared (JHK) imaging of the Seyfert 2 galaxy NGC 5252, taken with the IRAC2 array on the 2.2m telescope at ESO, La Silla. The unresolved and...

Context. The fundamental properties of brown dwarfs evolve with age. Models describing the evolution of luminosities and effective temperatures, among other...

Aims: We aim at obtaining near-infrared photometry and deriving the mass, age, temperature, and surface gravity of WISE J085510.74-071442.5 (J0855-0714), which...

Aims: The characterisation of the stellar population in young high-mass star-forming regions allows fundamental cluster properties like distance and age to be...

Context. Primitive asteroids contain complex organic material and ices relevant to the origin of life on Earth. These types of asteroids are the target of...

We report near-infrared (0.9-2.3 mu m) spectral observations of the bare nucleus of comet 124P/Mrkos taken on two different nights using the Near Infrared...

Context. The discovery of new massive star clusters and massive stellar populations in previously known clusters in our Galaxy by means of infrared studies has...
