Thirteen dwarf galaxies have recently been found to host radio-selected accreting massive black hole (MBH) candidates, some of which are “wandering” in the outskirts of their hosts. We present 9 GHz Very Long Baseline Array (VLBA) observations of these sources at milliarcsecond resolution. Our observations have beam solid angles ∼104 times smaller than the previous Very Large Array (VLA) observations at 9 GHz, with comparable point-source sensitivities. We detect milliarcsecond-scale radio… 



A New Sample of (Wandering) Massive Black Holes in Dwarf Galaxies from High-resolution Radio Observations

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 sensitive, high-resolution

A VLBI Search for Radio Supernovae in Wolf-Rayet Galaxies

We have used the VLBI High-Sensitivity Array (VLBA with Very Large Array [VLA], Green Bank Telescope, and Arecibo) to search for young radio supernovae in three nearby Wolf-Rayet dwarf galaxies

A Chandra and HST View of WISE-selected AGN Candidates in Dwarf Galaxies

Reliably identifying active galactic nuclei (AGNs) in dwarf galaxies is key to understanding black hole (BH) demographics at low masses and constraining models for BH seed formation. Here we present

Outflows, Shocks, and Coronal Line Emission in a Radio-selected AGN in a Dwarf Galaxy

Massive black holes (BHs) in dwarf galaxies can provide strong constraints on BH seeds; however, reliably detecting them is notoriously difficult. High-resolution radio observations were recently

X-Ray and Ultraviolet Properties of AGNs in Nearby Dwarf Galaxies

We present new Chandra X-ray Observatory and Hubble Space Telescope observations of eight optically selected broad-line active galactic nucleus (AGN) candidates in nearby dwarf galaxies (z < 0.055).


We have made sensitive milliarcsecond-resolution radio images of the nearby merger galaxy Arp 299 at four epochs spread over 18 months between 2003 and 2005. The combined data revealed a total of 30

Multimessenger Signatures of Massive Black Holes in Dwarf Galaxies

Recent discoveries of massive black holes (MBHs) in dwarf galaxies suggest that they may have a more common presence than once thought. Systematic searches are revealing more candidates, but this

A Radio Continuum Study of Dwarf Galaxies: 6 cm Imaging of LITTLE THINGS

In this paper, we examine to what extent the radio continuum can be used as an extinction-free probe of star formation in dwarf galaxies. To that aim, we observe 40 nearby dwarf galaxies with the

A New Sample of Low-Mass Black Holes in Active Galaxies

We present an expanded sample of low-mass black holes (BHs) found in galactic nuclei. Using standard virial mass techniques to estimate BH masses, we select from the Fourth Data Release of the Sloan

An actively accreting massive black hole in the dwarf starburst galaxy Henize 2-10

It is confirmed that nearby star-forming dwarf galaxies can indeed form massive black holes, and that by implication so can their primordial counterparts, and the lack of a substantial spheroidal component in Henize 2-10 indicates that supermassive black-hole growth may precede the build-up of galaxy spheroids.
