. The day after reaching Corydon, Edwin Hubble and Jack Roberts walked on west to Wyandotte Cave, where they explored the tight squeeze known as Worm Alley. Jack set his Brownie camera on a rocky ledge and scooted around in time to get his profile into the photo -- his only portrait with his hero Hubble. Photograph by Jack Roberts. Comments by John R.

... 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. ...
