The Apparent Host Galaxy of PKS 1413+135: Hubble Space Telescope,* ASCA, and Very Long Baseline Array ** Observations
HST ASCA
2014/12/26
PKS 1413+135 (z = 0.24671) is one of very few radio-loud active galactic nuclei (AGNs) with an apparent spiral host galaxy. Previous authors have attributed its nearly exponential infrared cutoff to h...
Investigation of Herbig Ae /Be stars in the near -infrared with a long baseline interferometer
Long baseline Stars Near infrared interferometry The dust
2014/12/9
We have conducted the first systematic study of Herbig Ae/Be stars using the technique of long baseline spatial interferometry in the near-infrared, with the objective of characterizing the distributi...
Very Long Baseline Array Imaging of Parsec-scale Jet Structures in Radio-loud Narrow-line Seyfert 1 Galaxies
Long Baseline Array Imaging Radio-loud Narrow-line Seyfert

We conducted very long baseline interferometry (VLBI) observations of five radio-loud narrow-line Seyfert 1 (NLS1) galaxies in milliarcsecond resolutions at 1.7 GHz (18 cm) using the Very Long Baselin...
Imaging "Pinwheel"nebulae with optical long-baseline interferometry
techniques high angular resolution – techniques interferometric – binaries close – stars

Dusty Wolf-Rayet stars are few but remarkable in terms of dust production rates (up to ˙M = 10−6M⊙/yr). Infrared excesses associated to mass-loss are found in the sub-types WC8 and WC9. Few WC9d...
