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

, 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]

, 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]

Journal 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)

, 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-

First Results from the rapid-response spectrophotometric characterization of Near-Earth Objects [PDF]

, 2019
As part of our multi-observatory, multi-filter campaign, we present \rmi color observations of 82 Near-Earth Objects (NEOs) obtained with the RATIR instrument on the 1.5m robotic telescope at the San Pedro Martir's National Observatory in Mexico.

Bispectrum speckle interferometry observations and radiative transfer modelling of the red supergiant NML Cyg: Multiple dust-shell structures evidencing previous superwind phases [PDF]

, 2001
(abridged) NML Cyg is a highly evolved OH/IR supergiant and supposed to be among the most luminous supergiants in the galaxy. We present the first diffraction limited 2.13micron observations of NML Cyg with 73mas resolution.

ISO observations and models of galaxies with Hidden Broad Line Regions

, 2005
We present ISO mid-infrared spectrophotometry and far-infrared photometry of galaxies with Hidden Broad Line Regions (HBLR). We also present radiative transfer models of their spectral energy distributions which enable us to separate the contributions ...
