Mid-Infrared Images of Luminous Infrared Galaxies in a Merging Sequence [PDF]

, 1998
We report mid-infrared observations of several luminous infrared galaxies (LIGs) carried out with the Infrared Space Observatory. Our sample was chosen to represent different phases of a merger sequence of galaxy-galaxy interaction with special emphasis ...

On the infrared behaviour of Gluons and Ghosts in Ghost-Antighost symmetric gauges [PDF]

, 2003
To investigate the possibility of a ghost-antighost condensate the coupled Dyson--Schwinger equations for the gluon and ghost propagators in Yang--Mills theories are derived in general covariant gauges, including ghost-antighost symmetric gauges.

Room temperature mid-infrared fibre photoluminescence and lasing beyond 5 μm in Ce3+ -doped chalcogenide glass – INVITED [PDF]

EPJ Web of Conferences, 2023
We review here our recent work in achieving mid-infrared (MIR) fibre lasing beyond 5 µm wavelength in Ce3+-doped selenide-chalcogenide fibre, as well as the observed photoluminescence in samples of the same composition but in particulate and bulk glass ...

Polycyclic Aromatic Hydrocarbon Emission within Lyα Blobs [PDF]

, 2011
We present Spitzer observations of Lyα blobs (LABs) at z = 2.38-3.09. The mid-infrared ratios (4.5 μm/8 μm and 8 μm/24 μm) indicate that ~60% of LAB infrared counterparts are cool, consistent with their infrared output being dominated by star formation ...

Developments for collective Thomson scattering equipment with a sub-THz gyrotron in LHD [PDF]

EPJ Web of Conferences, 2019
Plan of collective Thomson scattering (CTS) experiment for the Large Helical Device (LHD) in NIFS with a 303 GHz gyrotron is under way. Use of a sub-THz gyrotron expands the CTS-applicable region of plasma parameters.

Cosmological infrared subtractions & infrared-safe computables

SciPost Physics
Cosmological observables in perturbation theory turn out to be plagued with infrared divergences, which represents both a conceptual and computational challenge. In this paper we present a proof of concept for a systematic procedure to remove these divergences in a large class of scalar cosmological integrals and consistently define an infrared safe ...

A Low Signal-to-Noise Ratio Infrared Small-Target Detection Network

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Space-based infrared detection technology is critical to space situational awareness, playing a significant role in noncooperative space object detection, threat perception, and space target surveillance.

Neutral Gas Outflows and Inflows in Infrared-Faint Seyfert Galaxies

, 2009
Previous studies of the Na I D interstellar absorption line doublet have shown that galactic winds occur in most galaxies with high infrared luminosities.

The Vela and Geminga pulsars in the mid-infrared [PDF]

, 1999
The Vela and Geminga pulsars are rotation powered neutron stars, which have been identified in various spectral domains, from the near-infrared to hard $\gamma$-rays.
