The THESEUS Space Mission and the Infrared Telescope Calibration Unit

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT The Transient High‐Energy Sky and Early Universe Surveyor (THESEUS) is an ESA M7 mission concept currently in Phase A, designed to exploit gamma‐ray bursts to probe the early Universe while advancing multi‐messenger and time‐domain astrophysics. To achieve its ambitious goals, THESEUS will combine wide‐band x‐ray and gamma‐ray monitors with an

Near-infrared surface photometry of a sample of barred galaxies [PDF]

open access: yes, 2007
We have obtained deep J and Ks images of a sample of nine barred galaxies in order to collect a reliable and homogeneous set of images to which N-body simulations of barred galaxies will be compared.

Feasibility Study for Application of Digitized Henize Mt. Wilson Michigan Southern Sky Hα$$ \boldsymbol{\alpha} $$ Survey Low‐Dispersive Spectral Plates for Searches for Anomalous and Highly Redshifted Objects

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT The goal of this study is to confirm the feasibility of the use of digitized low dispersive MtWilson Michigan Southern Sky Hα$$ \alpha $$ survey astronomical photographic plates for modern astrophysical research. The detection of highly redshifted objects, such as early galaxies and quasars, is fundamental to understanding the universe's ...

WISE Photometry of Galaxies within 10 Mpc

open access: yesThe Astronomical Journal
For photometry of galaxies in the infrared that extend to very low surface brightnesses, it is necessary to observe with telescopes in space. The Wide-field Infrared Survey Explorer (WISE) and NEOWISE provide sensitive all-sky access to mid-infrared flux

Infrared /JHK/ photometry of asteroids

open access: yesThe Astronomical Journal, 1982
We report JHK (1.2, 1.6, and 2.2 micron) photometry for 23 asteroids of various spectral types. All of the TRIAD asteroid classes were sampled. The C and S classes have distinct, infrared color domains. Most R-class asteroids fall within the S-color domain and the observed M asteroids fall within the C-color domain. The E asteroids have neutral colors.

Body‐integrated photonic biosensors: Illuminating the path to active healthcare

open access: yesFlexMat, EarlyView.
Body‐integrated photonic biosensors are promising tools for active healthcare. These optical devices can be worn, implanted, or swallowed to monitor health signals continuously. This review introduces key sensing modalities, including fluorescence, colorimetry, SPR, LSPR, SERS, and light‐modulating materials.

Improving Optical Photo-z Constraints for Dusty Star-forming Galaxies Using Submillimeter-based Priors

open access: yesThe Astrophysical Journal
Photometric redshifts (photo- z ’s) provide an efficient alternative to spectroscopic redshifts, enabling redshift estimation for large galaxy samples.

Infrared photometry of O stars

open access: yesThe Astrophysical Journal, 1983
The results of a survey of 50 O stars in the J, H, K, L, and M bands are described. The observations are described, and the fitting of reddening relations to them is discussed. The zero points in the reddening relations are related to the intrinsic colors of the samples of normal stars, and these are compared with theoretical colors.

Integration of cortical inputs in the lateral hypothalamus is dominated by the medial prefrontal cortex

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The lateral hypothalamus (LH) is a critical controller of innate behaviours such as feeding. It is anatomically connected to specific cortical areas. We mapped these areas using a combination of retrograde tracing and anterograde optogenetic circuit mapping.

SIMLA: The Spitzer Infrared Spectrograph Mapping Legacy Archive

open access: yesThe Astrophysical Journal Supplement Series
We present the Spitzer/IRS Mapping Legacy Archive (SIMLA); a complete set of mid-infrared spectral cubes built from low-resolution mapping-mode fixed-target observations from the Spitzer Infrared Spectrograph (IRS; 5.2–38 μ m, R ∼ 60–130).
