Spectrophotometry and Infrared Photometry of BL Lacertae [PDF]

open access: bronzeThe Astrophysical Journal, 1969
The absolute spectral-energy distribution of BL Lacertae from 0.315 to 2.2 μ indicates that the optical radiation might be a continuation of the observed radio synchrotron flux. The very steep slope of the spectral-energy distribution suggests that the object is not a quasi-stellar radio source.

Autotrophic and Heterotrophic Growth Conditions Modify Biomolecole Production in the Microalga Galdieria sulphuraria (Cyanidiophyceae, Rhodophyta) [PDF]

open access: yes, 2020
Algae have multiple similarities with fungi, with both belonging to the Thallophyte, a polyphyletic group of non-mobile organisms grouped together on the basis of similar characteristics, but not sharing a common ancestor.

Transit spectrophotometry of the exoplanet HD189733b. I. Searching for water but finding haze with HST NICMOS [PDF]

open access: yes, 2009
We present Hubble Space Telescope near-infrared transit photometry of the nearby hot-Jupiter HD189733b. The observations were taken with the NICMOS instrument during five transits, with three transits executed with a narrowband filter at 1.87 microns and

Detection of Solvents by Infrared Spectrophotometry [PDF]

open access: yesJournal of AOAC INTERNATIONAL, 1967
Abstract The solvent used in the recrystallization of a solid may be determined by use of the IR spectrum and gas cell. Recrystallized powders retain a minute amount of solvent which is not detectable in a KBr disk of the powder, but is detectable when a gas cell is vised.

Exoplanet Research with the Stratospheric Observatory for Infrared Astronomy (SOFIA)

open access: yes, 2017
When the Stratospheric Observatory for Infrared Astronomy (SOFIA) was conceived and its first science cases defined, exoplanets had not been detected. Later studies, however, showed that optical and near-infrared photometric and spectrophotometric follow-
