Shapley-Ames Galaxies in the Blue and Infrared [PDF]

The Astronomical Journal, 2004
The Shapley-Ames Catalog of 1276 galaxies with B < 12.5 is compared with the Sanders et al. all sky sample of the 629 galaxies with 60 m flux density > 5.24 Jy. The fraction of Shapley-Ames galaxies that are visible in the IR is found to increase from 0.006 for E or E/S0 galaxies to 0.384 for Sc galaxies.

The Mid-Infrared Spectra of Normal Galaxies [PDF]

The Astrophysical Journal, 2000
The mid-infrared spectra (2.5 to 5 and 5.7 to 11.6 mu) obtained by ISO-PHOT reveal the interstellar medium emission from galaxies powered by star formation to be strongly dominated by the aromatic features at 6.2, 7.7, 8.6 and 11.3 mu. Additional emission appears in-between the features, and an underlying continuum is clearly evident at 3-5 mu.

The THESEUS Space Mission and the Infrared Telescope Calibration Unit

Astronomische Nachrichten, Volume 347, Issue 6, July 2026.
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

An Indication of Gas Inflow in Clumpy Star-forming Galaxies near z ∼ 1: Lower Gas-phase Metallicities in Clumpy Galaxies Compared to Nonclumpy Galaxies

The Astrophysical Journal
Despite the ubiquity of clumpy star-forming galaxies at high-redshift, the origin of clumps are still largely unconstrained due to the limited observations that can validate the mechanisms for clump formation.

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

Astronomische Nachrichten, Volume 347, Issue 6, July 2026.
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 ...

Germanium‐Based Mid‐Infrared Integrated Photonics

Laser &Photonics Reviews, Volume 20, Issue 14, 22 July 2026.
The mid‐infrared (mid‐IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Photonics integration in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological ...

Dense Ionized Outflow with Five Narrow Components in a Dust-obscured Galaxy

The Astrophysical Journal
We present our discovery of a complex ionized outflow in SDSS J101034.28+372514.7 (J1010+3725), a dust-obscured galaxy (DOG) at z = 0.282. The Sloan Digital Sky Survey optical spectrum of J1010+3725 shows five narrow components with one broad component ...

Circular Differential Scattering Spectroscopy for the Characterization of Single Chiral Nanostructures: Fundamentals, Development, and Perspectives

National Materials, Volume 1, Issue 1, Page 48-71, July 2026.
Circular differential scattering (CDS) spectroscopy relies on a modified dark‐field optical microscope to study single chiral nanostructures, avoiding the averaging effects of ensemble methods. Recently achieving improved detection limits of 1.5%, this robust technique analyzes plasmonic chirality and molecular interactions, with the future goal of ...
