Multi-epoch, high spatial resolution observations of multiple T Tauri systems [PDF]

, 2017
Context. In multiple pre-main-sequence systems the lifetime of circumstellar disks appears to be shorter than around single stars, and the actual dissipation process may depend on the binary parameters of the systems. Aims.

Coherent imaging at the Diamond beamline I13

physica status solidi (a), Volume 208, Issue 11, Page 2522-2525, November 2011., 2011
Abstract The Diamond beamline I13 for imaging and coherence applications is dedicated to hard X‐ray imaging on the micro and nano‐lengthscale. Two independent stations will be operated in a separate building at a distance of 250 m from the source. The imaging branch will perform in‐line phase contrast imaging and tomography over a large field of view ...

Overview of the Near‐IR S0 Galaxy Survey (NIRS0S)

Advances in Astronomy, Volume 2011, Issue 1, 2011., 2011
An overview of the results of the near‐IR S0 galaxy survey (NIRS0S) is presented. NIRS0S is a magnitude‐ (mB ⩽ 12.5 mag) and inclination‐ (<65∘) limited sample of ̃200 nearby galaxies, mainly S0s, but includes also Sa and E galaxies. It uses deep Ks‐band images, typically reaching a surface brightness of 23.5 mag arcsec−2.
