Light and colour of cirrus, translucent and opaque dust in the high-latitude area of LDN 1642
K. Mattila, P. Väisänen, K. Lehtinen +2
We have performed a 5-colour surface photometric study of the high-galactic-latitude area of dark nebula LDN 1642. Scattered light properties are presented of diffuse, translucent…
Optical and UV surface brightness of translucent dark nebulae: Dust albedo, radiation field and fluorescence emission by H2
K. Mattila, M. Haas, L. K. Haikala +4
Photometry of the nebulae LDN1780, LDN1642 and LBN406 is used to derive scattering properties of dust and to investigate the presence of UV fluorescence emission by molecular hydro…
Digitization and astrometric calibration of Carte du Ciel photographic plates with Gaia~DR1
K. Lehtinen, T. Prusti, J. de Bruijne +6
We want to study whether the astrometric and photometric accuracies obtained for the Carte du Ciel plates digitized with a commercial digital camera are high enough for scientific…
Radio interferometric observation of an asteroid occultation
Jorma Harju, Kimmo Lehtinen, Jonathan Romney +5
The occultation of the radio galaxy 0141+268 by the asteroid (372) Palma on 2017 May 15 was observed using six antennas of the Very Long Baseline Array (VLBA). The shadow of Palma…
Spectrophotometric measurement of the Extragalacic Background Light
Kalevi Mattila, Kimmo Lehtinen, Petri Vaisanen +2
The Extragalactic Background Light (EBL) at UV, optical and NIR wavelengths consists of the integrated light of all unresolved galaxies along the line of sight plus any contributio…
