Extragalactic Results from the Infrared Space Observatory

, 2000
More than a decade ago the IRAS satellite opened the realm of external galaxies for studies in the 10 to 100 micron band and discovered emission from tens of thousands of normal and active galaxies.

Flexible and High‐Performance Perovskite‐Polymer Composites for Dual X‐Ray and Proton Direct Detection

Advanced Optical Materials, EarlyView.
A polymer–perovskite composite obtained by mechanochemical synthesis enables thick, tunable active layers for efficient absorption of highly penetrating ionizing radiation. Vertical‐electrode detectors achieve low X‐ray detection limits and high sensitivity direct 5 MeV proton sensing.

A Simple Model of the Radio–Infrared Correlation Depending on Gas Surface Density and Redshift

The Astrophysical Journal
We introduce a simple parametric model of the radio–infrared correlation (i.e., the ratio between the IR luminosity and the 1.4 GHz radio luminosity, q _IR ) by considering the energy loss rate of high-energy cosmic-ray (CR) electrons governed by ...

The Magnetic Fields of Starburst Galaxies. I. Identification and Characterization of the Thermal Polarization in the Galactic Disk and Outflow

The Astrophysical Journal, 2023
Far-infrared polarized emission by means of magnetically aligned dust grains is an excellent tracer of the magnetic fields (B-fields) in the cold phase of the galactic outflows of starburst galaxies.

Direct Photocurrent Detection of Optical Vortex Based on the Orbital Photo Galvanic Effect: Progress, Challenge, and Perspective

Advanced Science, EarlyView.
Direct orbital angular momentum (OAM) detection through the orbital photogalvanic effect offers a scalable route for integrated optoelectronics. This perspective evaluates symmetry‐driven material selection and demonstrates how electrode matrices enable the resolution of complex, mixed OAM modes.

Transient Terahertz Oscillations During Photoinduced Polarization Topology Reconfiguration in Ferroelectric Superlattices

Advanced Science, EarlyView.
Terahertz resonances in crystalline heterostructures could close a spectral gap between conventional electronics and photonics while opening new windows on non‐equilibrium lattice dynamics. Femtosecond optical screening of the depolarization field in epitaxial PbTiO3/SrTiO3 superlattices launches a collective polar mode that oscillates near 1 THz and ...

16 x 25 Ge:Ga Detector Arrays for FIFI LS [PDF]

, 2000
We are developing two-dimensional 16 x 25 pixel detector arrays of both unstressed and stressed Ge:Ga photoconductive detectors for far-infrared astronomy from SOFIA. The arrays, based on earlier 5 x 5 detector arrays used on the KAO, will be for our new
