... The formation of multiple images of a distant quasar by the gravitational lensing effect of a foreground galaxy may be very simply, and faithfully, accounted for by a wine glass experiment. Figure 1. In the wine glass experiment, a bright compact light source (at the top of the photo) serves as a distant quasar. The wine glass on the table distorts the light rays from the "quasar" and produces a caustic having with a triangular shape (see enlargement in Figure 3 ). ...
... The Third Catalog of Emission Line Stars (Herbig & Bell 1988) and the General Catalog of Herbig-Haro Objects (Reipurth 1994) have both been translated into hypertext and linked to other on-line material. ... In recent years astronomical catalogs have disappeared from the archival literature. ... This spring I received a request from Bo Reipurth of ESO to review his preliminary General Catalog of Herbig-Haro Objects (Reipurth 1994) before it was made available via anonymous FTP from the ESO FTP...

ARCSAT ID NUMBER: AS04 DESCRIPTIVE TITLE: Constraining the magnetic fields of transiting exoplanets through ground-based near-UV observations PI: Jake Turner OBSERVER(S): Jake Turner (Graduate Student: University of Virginia) Apurva Oza (Graduate Student: University of Virginia) Robin Leiter (Undergraduate Student The magnetic field of a transiting exoplanet can be constrained by observing asymmetries in their near-UV light curves (Vidotto, Jardine Helling 2011a; Vidotto et al. ...
... All the galaxies are divided into 4 groups depending on the environment type; every subsample contains more than 10 galaxies. ... An effect of environments is seen both for the nuclei and for the bulges: if we consider the clusters (Virgo and Ursa Ma jor) and group centers as dense environments and the field and group periphery as sparse environments, then in the dense environments the stellar populations of S0s are in average older by 45 Gyr than in the sparse ones. ...

... The then president of the Society, Mr. Robert Burke, appointed a committee of eight or ten members, most of whom had made smaller mirrors, as an instrument committee, with Mr. Thorpe as chairman. ... Seriously, the best practicable solution seemed to be to build a machine to do the grinding and polishing. ... It was decided to grind the edges of the mirror to make it truly circular, as the rough cast glass was some 3/8 inch longer on one diameter than on the other. ...

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...
We present a catalogue of galaxies for which spatially resolved data on their internal kinematics have been published; there is no apriori restriction regarding their morphological type. The catalogue lists the references to the articles where the data are published, as well as a coded description of these data: observed emission (E) or absorption (A) data, optical (O) or radio (R) data, velocity (V) or velocity dispersion (D), radial profile (1) or 2D field (2). ...
