Constraining the Galactic Center Dark Cluster with ELT/MICADO Observations

Sebastiano D. von Fellenberg, Matúš Labaj, Sean M. Ressler

The Galactic Center hosts the densest known stellar environment in the Milky Way, dominated by the massive black hole Sgr A* and the surrounding nuclear star cluster. Theory predic…

Ionization Structure and Metal Enrichment of the Galactic Center Minispiral Observed with JWST

Nicole M Ford, Mayura Balakrishnan, Sebastiano D. von Fellenberg +11

Sagittarius A* (Sgr A*) is the nearest quiescent supermassive black hole, and its proximity offers a unique opportunity to study its surrounding fuel supply. We leverage extensive…

A dynamical measure of the black hole mass in a quasar 11 billion years ago

R. Abuter, F. Allouche, A. Amorim +124

Tight relationships exist in the local universe between the central stellar properties of galaxies and the mass of their supermassive black hole. These suggest galaxies and black h…

Using the motion of S2 to constrain vector clouds around SgrA*

GRAVITY Collaboration, A. Foschi, R. Abuter +53

The dark compact object at the centre of the Milky Way is well established to be a supermassive black hole with mass , but the nature…

The JWST Galactic Center Survey -- A White Paper

Rainer Schoedel, Steve Longmore, Jonny Henshaw +111

The inner hundred parsecs of the Milky Way hosts the nearest supermassive black hole, largest reservoir of dense gas, greatest stellar density, hundreds of massive main and post ma…

Polarimetry and Astrometry of NIR Flares as Event Horizon Scale, Dynamical Probes for the Mass of Sgr A*

The GRAVITY Collaboration, R. Abuter, N. Aimar +66

We present new astrometric and polarimetric observations of flares from Sgr A* obtained with GRAVITY, the near-infrared interferometer at ESO's Very Large Telescope Interferometer…

Using the motion of S2 to constrain scalar clouds around SgrA*

GRAVITY Collaboration, A. Foschi, R. Abuter +67

The motion of S2, one of the stars closest to the Galactic Centre, has been measured accurately and used to study the compact object at the centre of the Milky Way. It is commonly…

Where intermediate-mass black holes could hide in the Galactic Centre: A full parameter study with the S2 orbit

The GRAVITY Collaboration, O. Straub, M. Bauböck +59

In the Milky Way the central massive black hole, SgrA*, coexists with a compact nuclear star cluster that contains a sub-parsec concentration of fast-moving young stars called S-st…

The young stars in the Galactic Center

Sebastiano von Fellenberg, Stefan Gillessen, Julia Stadler +11

We present a large spectroscopic survey of the Galactic Center using the SINFONI IFU at the VLT. Combining observations of the last two decades we compile s…

The mass distribution in the Galactic Centre from interferometric astrometry of multiple stellar orbits

GRAVITY Collaboration, R. Abuter, N. Aimar +62

The stars orbiting the compact radio source Sgr A* in the Galactic Centre are precision probes of the gravitational field around the closest massive black hole. In addition to adap…

Deep Images of the Galactic Center with GRAVITY

GRAVITY Collaboration, R. Abuter, N. Aimar +65

Stellar orbits at the Galactic Center provide a very clean probe of the gravitational potential of the supermassive black hole. They can be studied with unique precision, beyond th…

What stellar orbit is needed to measure the spin of the Galactic center black hole from astrometric data?

Idel Waisberg, Jason Dexter, Stefan Gillessen +11

Astrometric and spectroscopic monitoring of individual stars orbiting the supermassive black hole in the Galactic Center offer a promising way to detect general relativistic effect…

Probing the Gas Density in our Galactic Center: Moving Mesh Simulations of G2

Elad Steinberg, Re'em Sari, Orly Gnat +11

The G2 object has recently passed its pericenter passage in our Galactic Center. While the emission shows clear signs of tidal interaction, the change in the observed lumino…

The Post-Pericenter Evolution of the Galactic Center Source G2

P. M. Plewa, S. Gillessen, O. Pfuhl +9

In early 2014 the fast-moving near-infrared source G2 reached its closest approach to the supermassive black hole Sgr A* in the Galactic Center. We report on the evolution of the i…

An Update on Monitoring Stellar Orbits in the Galactic Center

Stefan Gillessen, Philipp Plewa, Frank Eisenhauer +9

Using 25 years of data from uninterrupted monitoring of stellar orbits in the Galactic Center, we present an update of the main results from this unique data set: A measurement of…
