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…

The 2014-2017 outburst of the young star ASASSN-13db: A time-resolved picture of a very low-mass star between EXors and FUors

A. Sicilia-Aguilar, A. Oprandi, D. Froebrich +13

ASASSN-13db is a M5-type star with a protoplanetary disk, the lowest mass star known to experience accretion outbursts. Since its discovery in 2013, it has experienced two outburst…

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…

Proper motions of molecular hydrogen outflows in the Rho Ophiuchi molecular cloud

M. Zhang, W. Brandner, H. Wang +6

We aim to take a census of molecular hydrogen emission line objects (MHOs) in the Rho Ophiuchi molecular cloud and to make the first systematic proper motion measurements of these…

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…
