Host galaxy magnitude of OJ 287 from its colours at minimum light
Mauri J. Valtonen, Lankeswar Dey, S. Zola +54
OJ 287 is a BL Lacertae type quasar in which the active galactic nucleus (AGN) outshines the host galaxy by an order of magnitude. The only exception to this may be at minimum ligh…
3C 294 revisited: Deep Large Binocular Telescope AO NIR images and optical spectroscopy
J. Heidt, A. Quirrenbach, N. Hoyer +11
Context. High redshift radio galaxies are among the most massive galaxies at their redshift, are often found at the center of protoclusters of galaxies, and are expected to evolve…
Isotope selective photodissociation of N2 by the interstellar radiation field and cosmic rays
Alan N. Heays, Ruud Visser, Roland Gredel +4
Photodissociation of 14N2 and 14N15N occurs in interstellar clouds, circumstellar envelopes, protoplanetary discs, and other environments due to UV radiation from stellar sources a…
GM 2-4 - a signpost for low and intermediate mass star formation
Tigran Khanzadyan, Tigran A. Movsessian, Chris J. Davis +3
We present a multi-wavelength study of the region towards the GM 2-4 nebula and the nearby source IRAS 05373+2340. Our near-infrared H2 1-0 S(1) line observations reveal various sh…
Abundances of PAHs in the ISM: Confronting Observations with Experimental Results
R. Gredel, Y. Carpentier, G. Rouille +3
We present recent UV laboratory spectra of various polycyclic aromatic hydrocarbons (PAHs) and explore the potential of these molecules as carriers of the DIBs. From a detailed com…
UWISH2 -- The UKIRT Widefield Infrared Survey for H2
D., Froebrich, C. J. +56
We present the goals and preliminary results of an unbiased, near-infrared, narrow-band imaging survey of the First Galactic Quadrant (10deg<l<65deg ; -1.3deg<b<+1.3deg). This area…
