The limb-darkened Arcturus; Imaging with the IOTA/IONIC interferometer
S. Lacour, S. Meimon, E. Thiebaut +14
This paper is an H band interferometric examination of Arcturus, a star frequently used as a spatial and spectral calibrator. Using the IOTA 3 telescope interferometer, we performe…
An original interferometric study of NGC 1068 with VISIR BURST mode images
A. Poncelet, C. Doucet, G. Perrin +2
We present 12.8 microns images of the core of NGC 1068 obtained with the BURST mode of the VLT/VISIR. We trace structures under the diffraction limit of one UT and we investigate t…
Mid-IR observations of NGC 1068 with VLT/VISIR
A. Poncelet, C. Doucet, G. Perrin +2
We present a speckle analysis of the active galactic nucleus (AGN) inside the archetype Seyfert type 2 galaxy NGC 1068. This study is based on 12.8 microns images obtained with the…
A new analysis of the nucleus of NGC 1068 with MIDI observations
A. Poncelet, G. Perrin, H. Sol
We present a new analysis of the very first mid-infrared N-band long-baseline interferometric observations of an extragalactic source: the nucleus of the Seyfert 2 galaxy NGC 1068,…
