M ⊙ black hole in NGC 7052 from HST observations of the nuclear gas disk 1
We present a Hubble Space Telescope (HST) study of the nuclear region of the E4 radio galaxy NGC 7052, which has a nuclear disk of dust and gas. The Second Wide Field and Planetary Camera (WFPC2) was used to obtain B, V and I broad-band images and an Hα+[NII] narrow-band image. The images yield the stellar surface brightness profile, the optical depth of the dust, and the flux distribution of t...
متن کاملCo Gas inside the Protoplanetary Disk Cavity in Hd 142527: Disk Structure from Alma
Inner cavities and annular gaps in circumstellar disks are possible signposts of giant planet formation. The young star HD 142527 hosts a massive protoplanetary disk with a large cavity that extends up to 140 au from the central star, as seen in continuum images at infrared and millimeter wavelengths. Estimates of the survival of gas inside disk cavities are needed to discriminate between clear...
متن کاملThe Nuclear Disk in the Dwarf Elliptical Galaxy Ngc 4486a1
Many ellipticals contain nuclear disks of dust and gas. Some ellipticals contain nuclear disks of stars that are distinct from the rest of the galaxy. We show that the dwarf E2 galaxy NGC 4486A contains both – it is a “Rosetta stone" object that tells us how nuclear disks evolve. Its properties suggest that, as accreted gas dissipates and settles toward the center, it forms stars and builds a s...
متن کاملA Nuclear Disk and massive BH in NGC 4342
We discuss photometric and spectroscopic data of the E/S0 galaxy NGC 4342, obtained with the Hubble Space Telescope (HST). This galaxy harbors, in addition to its outer disk, a very small, stellar disk in its nucleus. Jeans-modeling suggests the presence of a 3-6×10 8 M ⊙ black hole (BH) in the nucleus. This galaxy therefore deviates significantly from the correlation between BH mass and bulge ...
متن کاملGlobal Spiral Modes in NGC 1566: Observations and Theory
We present an observational and theoretical study of the spiral structure in galaxy NGC 1566. A digitized image of NGC 1566 in I-band, obtained with the Australian National University 30in telescope, was used for measurements of the radial dependence of amplitude variations in the spiral arms. The azimuthal variations of the surface brightness in the I-band are about ±7 % at 50 radius and incre...
