... We also demonstrate that for a source having a Gaussian surface brightness profile, a single longbaseline estimate of refractive substructure determines an absolute minimum brightness temperature, if the scattering properties along a given line of sight are known, and that this minimum accurately approximates the apparent brightness temperature over a wide range of total flux densities. ... At 18 cm, the brightness temperature estimate after accounting for refractive noise is Tb ~ 7 ґ 1012 K . ...

Appendix A: Derivation of the Secondary Sag as a Function of Telescope Altitude . One-half of the secondary support structure consists of the two rods shown in Figure 9 plus the opposing rods on the other side of the secondary cage. The total tension force on a single rod can be decomposed into a thermal component and a base tension that is set at the time when the rods are originally tensioned with the turnbuckles. ... The axial force balance equation is then given by . ...

. A distribution list is very useful where a group of users need to communicate amongst themselves on a regular basis. Each list is given a name just like any other user. By addressing a message to the list name, the sender can be sure that everyone will receive a copy. You cannot set up a distribution list yourself. Ask your system administrator to set one up for you.

... arXiv.org . astro-ph . ... We fit the near-infrared to radio spectral energy distributions of 30 luminous and ultra-luminous infrared galaxies with pure starburst models or models that include both starburst and AGN components to determine important physical parameters for this population of objects. In particular we constrain the optical depth towards the luminosity source, the star formation rate, the star formation efficiency and the AGN fraction. ...
