Near-infrared photometry of carbon stars [PDF]
Monthly Notices of the Royal Astronomical Society, 2006 Abstract Near-infrared, JHKL, photometry of 239 Galactic C-rich variable stars is presented and discussed. From these and published data, the stars were classified as Mira or non-Mira variables, and amplitudes and pulsation periods, ranging from 222 to 948 d for the Miras, were determined for most of them.

H<sub>2</sub>S-Releasing Aspirin Nanoparticles Alleviate Endometriosis and Associated Anxiety. [PDF]
Adv Sci (Weinh)Albumin nanoparticles loaded with an H2S‐releasing aspirin derivative (ACS14) hitchhiking neutrophils after intraperitoneal injection and preferentially accumulate in endometriosis lesions in mice. The treatment suppresses lesion growth by regulating PI3K/Akt and reduces inflammation by inhibiting NF‐κB.

The Astrophysical Journal, 1974 A set of observations of Titan at wavelengths from 1.6 through 34 microns shows that Titan has a remarkably low albedo near 1.6 micron. Thermal flux observations for 10 years at 10.6 microns and for 5 years at 21 microns suggest that the thermal properties of Titan remained constant over this period and are independent of phase.

Near-infrared photometry of WISE J085510.74–071442.5 [PDF]
Astronomy & Astrophysics, 2016 (Abridged) We aim at measuring the near-infrared photometry, and deriving the mass, age, temperature, and surface gravity of WISE J085510.74-071442.5 (J0855-0714), which is the coolest known object beyond the Solar System as of today. We use publicly available data from the archives of the HST and the VLT to determine the emission of this source at 1 ...

Infrared photometry of z 1 3C quasars [PDF]
Monthly Notices of the Royal Astronomical Society, 2000 We present JHKL' photometry of a complete sample of steep-spectrum radio-loud quasars from the revised 3CR catalogue in the redshift range 0.65 < z < 1.20. After correcting for contributions from emission lines and the host galaxies, we investigate their spectral energy distributions (SEDs) around 1 micron.

Absolute Calibration. III. Improved Absolute Calibration for the Visible through the Mid-infrared
The Astronomical Journal, 2023 We propose Sirius as an improved zero-point-defining star and calibrate its spectrum to an accuracy of ∼0.6% in both the visible and infrared. This result is based on a newly derived independent calibration in the visible of similar accuracy to the ...

The Farmer: A Reproducible Profile-fitting Photometry Package for Deep Galaxy Surveys
The Astrophysical Journal Supplement Series, 2023 While space-borne optical and near-infrared facilities have succeeded in delivering a precise and spatially resolved picture of our Universe, their small survey area is known to underrepresent the true diversity of galaxy populations.

Astrometry and Photometry for ≈1000 L, T, and Y Dwarfs from the UKIRT Hemisphere Survey
The Astronomical Journal, 2023 We present the positions, proper motions, and near-infrared photometry for 966 known objects with spectral types later than M that were observed as part of the the UKIRT Hemisphere Survey (UHS).

Measuring the Dust Attenuation Curves of SINGS/KINGFISH Galaxies Using Swift/UVOT Photometry
The Astrophysical Journal, 2023 We present Swift/Ultraviolet Optical Telescope (UVOT) integrated light photometry of the Spitzer Infrared Nearby Galaxies Survey (SINGS) and the Key Insights on Nearby Galaxies: A Far-Infrared Survey with Herschel (KINGFISH) samples of nearby galaxies ...
