Cosmological infrared subtractions & infrared-safe computables

open access: yesSciPost 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

open access: yesIEEE 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.

Outflows in rho Ophiuchi as Seen with the Spitzer Infrared Array Camera

open access: yes, 2009
Using the IRAC images from the Spitzer c2d program, we have made a survey of mid-infrared outflows in the rho Ophiuchi molecular cloud. Extended objects that have prominent emission in IRAC channel 2 (4.5 micron) compared to IRAC channel 1 (3.6 micron ...

Mid-infrared Selection of Active Galactic Nuclei with the Wide-Field Infrared Survey Explorer. I. Characterizing WISE-selected Active Galactic Nuclei in COSMOS [PDF]

open access: yes, 2012
The Wide-field Infrared Survey Explorer (WISE) is an extremely capable and efficient black hole finder. We present a simple mid-infrared color criterion, W1 – W2 ≥ 0.8 (i.e., [3.4]–[4.6] ≥0.8, Vega), which identifies 61.9 ± 5.4 active galactic nucleus ...

The Spitzer Archival Far-InfraRed Extragalactic Survey [PDF]

open access: yes, 2015
We present the Spitzer Archival Far-InfraRed Extragalactic Survey (SAFIRES). This program produces refined mosaics and source lists for all far-infrared extragalactic data taken during the more than six years of the cryogenic operation of the Spitzer ...

How to characterize figures of merit of two-dimensional photodetectors

open access: yesNature Communications, 2023
Photodetectors based on two-dimensional (2D) materials have been the focus of intensive research and development over the past decade. However, a gap has long persisted between fundamental research and mature applications.

Photoelectric sensor output controlled by eyeball movements [PDF]

open access: yes, 1965
The difference between the infrared absorption of the iris and infrared reflectivity of the eyeball controls the operation of a device consisting of an infrared source and amplifier, a cadmium selenide infrared sensor, and an infrared ...

High Resolution Mid-Infrared Imaging of Ultraluminous Infrared Galaxies [PDF]

open access: yes, 1999
Observations of ultraluminous infrared galaxies (ULIRGs) with an achieved resolution approaching the diffraction limit in the mid-infrared from 8 - 25 $\mu$m using the Keck Telescopes are reported.

The ubiquitin ligase RNF115 is required for the clearance of damaged lysosomes

open access: yesFEBS Letters, EarlyView.
Upon lysosomal rupture, an E3 ubiquitin ligase RNF115 translocates from the cytosol to the damaged lysosomal membrane. Moreover, RNF115 depletion impairs the clearance of damaged lysosomes, identifying it as a key regulator of lysosomal quality control.

High discrimination infrared polarimetry via intrinsic anisotropic photogating in black phosphorus meta-polarization detectors

open access: yesNature Communications
Filterless miniaturized polarization photodetectors are essential for next-generation ultracompact optical and optoelectronic systems. However, achieving high polarization discrimination and high sensitivity over a broad wavelength range based on a ...
