First proton-proton collisions at the LHC as observed with the ALICE detector: measurement of the charged particle pseudorapidity density at = 900 GeV
ALICE Collaboration
On 23rd November 2009, during the early commissioning of the CERN Large Hadron Collider (LHC), two counter-rotating proton bunches were circulated for the first time concurrently i…
The Incidence of Active Galactic Nuclei in Pure Disk Galaxies: The Spitzer View
S. Satyapal, T. Boeker, W. Mcalpine +3
We have conducted a high-resolution spectroscopic study using Spitzer of 18 bulgeless (Sd/Sdm) galaxies that show no definitive signatures of nuclear activity in their optical spec…
Rotationally Warm Molecular Hydrogen in the Orion Bar
Gargi Shaw, G. J. Ferland, W. J. Henney +5
The Orion Bar is one of the nearest and best-studied photodissociation or photon-dominated regions (PDRs). Observations reveal the presence of H2 lines from vibrationally or rotati…
Dust-Bounded ULIRGs? Model Predictions for Infrared Spectroscopic Surveys
N. P. Abel, C. Dudley, Jacqueline Fischer +2
The observed faintness of infrared fine-structure line emission along with the warm far-infrared (FIR) colors of ultraluminous infrared galaxies (ULIRGs) is a long-standing problem…
