A precise interstellar dust extinction law is critically important to interpret observations. There
are two indicators of extinction: the color excess ratio (CER) and the relative extinction …

Context. The environment of Sagittarius A*(Sgr A*), the central black hole of the Milky Way,
is the only place in the Universe where we can currently study the interaction between a …

The nuclear disk is a dense stellar structure at the centre of the Milky Way, with a radius of~
150 pc (ref.). It has been a place of intense star formation in the past several tens of millions …

Context. The nuclear stellar disc (NSD) is, together with the nuclear star cluster (NSC) and
the central massive black hole, one of the main components in the central parts of our Milky …

As a young massive cluster in the central molecular zone, the Arches cluster is a valuable
probe of the stellar initial mass function (IMF) in the extreme Galactic center environment …

Context. The Milky Way nuclear star cluster (MWNSC) is a crucial laboratory for studying the
galactic nuclei of other galaxies, but its properties have not been determined unambiguously …

We report the first star formation history study of the Milky Ways nuclear star cluster (NSC),
which includes observational constraints from a large sample of stellar metallicity …

Abstract The Milky Way's centre is the closest galaxy nucleus and the most extreme
environment in the Galaxy. Although its volume is less than 1% of that of the Galactic Disk …

Context. The high extinction and extreme source crowding of the central regions of the Milky
Way are serious obstacles to the study of the structure and stellar population of the Galactic …

Context. The extreme extinction (AV~ 30 mag) and its variation on arc-second scales
towards the Galactic centre hamper the study of its stars. Analysis of them is restricted to the …
