This paper describes the CMS trigger system and its performance during Run 1 of the LHC. The trigger system consists of two levels designed to select events of...
The CO structure of NGC 7027 - A bipolar nebula in the making
Intermediate resolution mapping and limited off-center spectroscopy of the post-main-sequence molecular outflow source NGC 7027 are presented. The CO envelope...
The co-evolution of strong AGN and central galaxies in different environments
We exploit a sample of 80 000 Sloan Digital Sky Survey central galaxies to investigate the effect of active galactic nucleus (AGN) feedback on their evolution...
The Cocoon nebula and its ionizing star: do stellar and nebular abundances agree?
Context. Main-sequence massive stars embedded in an H ii region should have the same chemical abundances as the surrounding nebular gas+dust. The Cocoon nebula...
The coincidence and angular clustering of Chandra and SCUBA sources
We explore the relationship between the hard X-ray and submillimetre populations using deep Chandra observations of a large, contiguous SCUBA survey. In...
Context. Radio surveys of early-type stars have revealed a number of non-thermal emitters. Most of these have been shown to be binaries, where the collision...
The color signature of the transit of HD 209458: discrepancies between stellar atmospheric models and observations
Exoplanetary transits produce a double-horned color signature that is distinct from both binaries and blends and can thus be used to separate exoplanets from...
The Color-Magnitude Distribution of Field Galaxies to z~3: The Evolution and Modeling of the Blue Sequence
Using deep NIR VLT ISAAC and optical HST WFPC2 imaging in the HDF-S and MS 1054-03, we study the rest-frame UV-to-optical colors and magnitudes of galaxies to z...
The compact multi-planet system GJ 9827 revisited with ESPRESSO★
GJ 9827 is a bright, nearby K7V star orbited by two super-Earths and one mini-Neptune on close-in orbits. The system was first discovered using K2 data and then...
