We present microvariability observations of OJ 287, taken during a small flare in January 1994. We can follow the behaviour of OJ 287 during the whole flare...
Microwave spectro-polarimetry of matter and radiation across space and time
This paper discusses the science case for a sensitive spectro-polarimetric survey of the microwave sky. Such a survey would provide a tomographic and dynamic...
Mid- and far-infrared spectroscopy of nucleobases: molar extinction coefficients, integrated molar absorptivity, and temperature dependence of the main bands
The nucleobases, namely the purines adenine and guanine and the pyrimidines cytosine, thymine, and uracil, are the key monomers of the information polymers DNA...
Mid-infrared Galaxy Morphology from the Spitzer Survey of Stellar Structure in Galaxies (S4G): The Imprint of the De Vaucouleurs Revised Hubble-Sandage Classification System at 3.6 μm
Spitzer Space Telescope Infrared Array Camera imaging provides an opportunity to study all known morphological types of galaxies in the mid-IR at a depth...
Mid-infrared imaging- and spectro-polarimetric subarcsecond observations of NGC 1068
We present subarcsecond 7.5-13 μm imaging- and spectro-polarimetric observations of NGC 1068 using CanariCam on the 10.4-m Gran Telescopio CANARIAS. At all...
Mid-infrared sources in the ELAIS Deep X-ray Survey
We present a cross-correlation of the European Large Area Infrared Space Observatory (ISO) survey (ELAIS) with the ELAIS Deep X-ray Survey of the N1 and N2...
Mid-infrared Spectral Variability Atlas of Young Stellar Objects
Optical and near-infrared variability is a well-known property of young stellar objects. However, a growing number of recent studies claim that a considerable...
Mid-infrared spectroscopy of infrared-luminous galaxies at z ~ 0.5-3
We present results on low-resolution mid-infrared (MIR) spectra of 70 IR-luminous galaxies obtained with the infrared spectrograph (IRS) onboard Spitzer. We...
Mid-infrared spectrum of the zodiacal light observed with ISOPHOT
We present 29 mid-infrared spectra of the zodiacal light distributed over the sky. The observed 5.9-11.7 mu m spectral shapes are well represented by blackbody...
