VIBRATIONALLY EXCITED HCN IN THE LUMINOUS INFRARED GALAXY NGC 4418 [PDF]
, 2010 Infrared pumping and its effect on the excitation of HCN molecules can be important when using rotational lines of HCN to probe dense molecular gas in galaxy nuclei.

Mid-Infrared Spectral Diagnostics of Luminous Infrared Galaxies [PDF]
AIP Conference Proceedings, 2010 We present a statistical analysis of 248 luminous infrared galaxies (LIRGs) which comprise the Great Observatories All‐sky LIRG Survey (GOALS) observed with the Infrared Spectrograph (IRS) on‐board Spitzer in the rest‐frame wavelength range between 5 and 38 μm.

Functional Ecology, Volume 39, Issue 10, Page 2573-2587, October 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract The light climate at high latitudes, in particular the extended twilight of winter and the reduced diel variation in light level in midsummer and midwinter, potentially constrains visual function and the synchronisation of temporal organisation in polar species. In this

Searching for Dark Galaxies with H I Detection from the Arecibo Legacy Fast ALFA (ALFALFA) Survey
The Astrophysical Journal Supplement SeriesWe present a catalog of 142 dark galaxy candidates in a region covered by the Arecibo Legacy Fast ALFA (ALFALFA) survey. We start with 344 ALFALFA H i sources without optical counterparts and remove those that do not seem to have a dark galaxy origin. To

A Large Mass of H_2 in the Brightest Cluster Galaxy in Zwicky 3146 [PDF]
, 2006 We present the Spitzer/IRS mid-infrared spectrum of the infrared-luminous (L_(IR) = 4 × 10^(11) L_☉) brightest cluster galaxy (BCG) in the X-ray-luminous cluster Zwicky 3146 (Z3146; z = 0.29).

High-Resolution Imaging of Warm and Dense Molecular Gas in the Nuclear Region of the Luminous Infrared Galaxy NGC 6240 [PDF]
, 2007 We present ~2'' resolution CO (3-2), HCO+(4-3), and 880 μm continuum images of the luminous infrared galaxy NGC 6240 obtained at the Submillimeter Array. We find that the spatially resolved CO (3-2), HCO + (4-3), and the 880 μm emission peaks between the

Reassessing the Relationship Between Meteor Radio Afterglows and Optical Persistent Trains
Journal of Geophysical Research: Space Physics, Volume 130, Issue 9, September 2025.Abstract Meteor radio afterglows (MRAs) and optical persistent trains (PTs) are two types of long‐lived phenomena which are occasionally observed following the occurrence of a meteor. Both phenomena are thought to be produced by intrinsic emission mechanisms; PTs have been associated with chemiluminescent reactions between meteoric metals and ...
