Mid Infrared Polarisation of Ultraluminous Infrared Galaxies [PDF]
Astronomy & Astrophysics, 2001 The mid infrared polarisation properties of four Ultraluminous Infrared Galaxies (ULIRGs) have been investigated by broad band filter observations with the ISOCAM instrument on board the Infrared Space Observatory (ISO).

Infrared Spectroscopy—Mid-infrared, Near-infrared, and Far-infrared/Terahertz Spectroscopy
Analytical Sciences, 2021 This article aims to overview infrared (IR) spectroscopy. Simultaneously, it outlines mid-infrared (MIR), near-infrared (NIR), and far-infrared (FIR) or terahertz (THz) spectroscopy separately, and compares them in terms of principles, characteristics, advantages, and applications.

Infrared analysis of propagators and vertices of Yang--Mills theory in Landau and Coulomb gauge [PDF]
, 2006 The infrared behaviour of gluon and ghost propagators, ghost-gluon vertex and three-gluon vertex is investigated for both the covariant Landau and the non-covariant Coulomb gauge.

High efficiency and fast van der Waals hetero-photodiodes with a unilateral depletion region
Nature Communications, 2019 Photovoltaic devices based on 2D materials still suffer from low quantum efficiencies due to interfacial charge recombination and inefficient contacts.

International Journal of Modern Physics E, 2009 We prove that Nambu–Jona-Lasinio model is an exact description of infrared Quantum ChromoDynamics (QCD) deriving it from QCD Lagrangian. The model we obtain is renormalizable and confining but, taking very small momenta fixes completely all the parameters of the Nambu–Jona-Lasinio model through those of QCD.

Spitzer Observations of GX17+2: Confirmation of a Periodic Synchrotron Source [PDF]
, 2011 GX17+2 is a low-mass X-ray binary (LMXB) that is also a member of a small family of LMXBs known as "Z-sources" that are believed to have persistent X-ray luminosities that are very close to the Eddington limit. GX17+2 is highly variable at both radio and

Remote Sensing, 2023 Velocity estimation of space moving targets is a key part of space situational awareness. However, most of the existing methods do not consider the satellite observation process, and the performance mainly depends on the preset target motion state, which

Infrared Gluon and Ghost Propagators [PDF]
, 1996 We derive the form of the infrared gluon propagator by proving a mapping in the infrared of the quantum Yang-Mills and $\lambda\phi^4$ theories. The equivalence is complete at a classical level. But while at a quantum level, the correspondence is spoiled

The infrared counterpart to the magnetar 1RXS J170849.0-400910 [PDF]
, 2006 We have analyzed both archival and new infrared imaging observations of the field of the Anomalous X-ray Pulsar 1RXS J170849.0-400910, in search of the infrared counterpart.
