From Supermassive Black Holes to Dwarf Elliptical Nuclei: a Mass Continuum

open access: yes, 2006
Considerable evidence suggests that supermassive black holes reside at the centers of massive galactic bulges. At a lower galactic mass range, many dwarf galaxies contain extremely compact nuclei that structurally resemble massive globular clusters.

Supermassive Black Hole Growth in Hierarchically Merging Nuclear Star Clusters

open access: yesThe Astrophysical Journal
Supermassive black holes are prevalent at the centers of massive galaxies, and their masses scale with galaxy properties, increasing evidence suggesting that these trends continue to low stellar masses.

Molecular characteristics of segment 5, a unique fragment encoding two partially overlapping ORFs in the genome of rice black-streaked dwarf virus.

open access: yesPLoS ONE, 2019
Rice black-streaked dwarf virus (RBSDV), a ds-RNA virus in Fijivirus genus with family Reoviridae, which is transmitted by the small brown planthopper, is responsible for incidence of maize rough dwarf disease (MRDD) and rice black-streaked dwarf disease

The Host Galaxy and Central Engine of the Dwarf AGN POX 52

open access: yes, 2008
We present new multi-wavelength observations of the dwarf Seyfert 1 galaxy POX 52 in order to investigate the properties of the host galaxy and the active nucleus, and to examine the mass of its black hole, previously estimated to be ~ 10^5 M_sun. Hubble

The symbiotic system AG Draconis. Soft X-ray bremsstrahlung from the nebulae

open access: yes, 2010
The modeling of UV and optical spectra emitted from the symbiotic system AG Draconis, adopting collision of the winds, predicts soft X-ray bremsstrahlung from nebulae downstream of the reverse shock with velocities > 150 km/s and intensities comparable ...
