Intermediate-mass black holes
JE Greene, J Strader, LC Ho - Annual Review of Astronomy and …, 2020 - annualreviews.org
We describe ongoing searches for intermediate-mass black holes with M BH≈ 10–105 M⊙.
We review a range of search mechanisms, both dynamical and those that rely on accretion …

Streams, substructures, and the early history of the Milky Way
A Helmi - Annual Review of Astronomy and Astrophysics, 2020 - annualreviews.org
The advent of the second data release of the Gaia mission, in combination with data from
large spectroscopic surveys, is revolutionizing our understanding of the Galaxy. Thanks to …

Evidence from the h3 survey that the stellar halo is entirely comprised of substructure
In the ΛCDM paradigm, the Galactic stellar halo is predicted to harbor the accreted debris of
smaller systems. To identify these systems, the H3 Spectroscopic Survey, combined with …

Ultra-light dark matter
EGM Ferreira - The Astronomy and Astrophysics Review, 2021 - Springer
Ultra-light dark matter is a class of dark matter models (DM), where DM is composed by
bosons with masses ranging from 10^-24\, eV< m< eV 10-24 eV< m< eV. These models …

[HTML][HTML] From galactic bars to the hubble tension: Weighing up the astrophysical evidence for milgromian gravity
Astronomical observations reveal a major deficiency in our understanding of physics—the
detectable mass is insufficient to explain the observed motions in a huge variety of systems …

Detection of the Keplerian decline in the Milky Way rotation curve
Our position inside the Galactic disc has previously prevented us from establishing an
accurate rotation curve (RC). The advent of Gaia and its third data release (Gaia DR3) made …

Reconstructing the last major merger of the Milky Way with the H3 survey
Several lines of evidence suggest that the Milky Way underwent a major merger at z∼ 2 with
the Gaia-Sausage-Enceladus (GSE) galaxy. Here we use H3 Survey data to argue that GSE …
