Active galactic nuclei (AGN) are energetic astrophysical sources powered by accretion onto
supermassive black holes in galaxies, and present unique observational signatures that …

Intermediate-mass black holes (IMBHs), with masses in the range 1 0 0–1 0 6 M⊙, are the
link between stellar-mass BHs and supermassive BHs (SMBHs). They are thought to be the …

Hard X-ray (≥ 10 keV) observations of active galactic nuclei (AGNs) can shed light on some
of the most obscured episodes of accretion onto supermassive black holes. The 70-month …

We present a sample of 40 active galactic nucleus (AGN) in dwarf galaxies at redshifts z≲
2.4. The galaxies are drawn from the Chandra COSMOS-Legacy survey as having stellar …

We use deep Chandra X-ray imaging to measure the distribution of specific black hole
accretion rates (LX relative to the stellar mass of the galaxy) and thus trace active galactic …

We present a sample of nearby dwarf galaxies with radio-selected accreting massive black
holes (BHs), the majority of which are non-nuclear. We observed 111 galaxies using …

We combine deep optical and radio data, from the Hyper Suprime-Cam and the Low-
Frequency Array (LOFAR), respectively, to study 78 radio active galactic nuclei (AGN) in …

The finding of active galactic nuclei (AGNs) in dwarf galaxies has important implications for
galaxy evolution and supermassive black hole formation models. Yet, how AGNs in dwarf …

We present a new relationship between central black hole (BH) mass and host galaxy stellar
bulge mass extending to the lowest BH masses known in dwarf galaxies (M BH≲ 10 5 M⊙; …
