Black-hole masses, accretion rates and hot- and cold-mode accretion in radio galaxies at z~1
Cristina A. C. Fernandes, Matt J. Jarvis, Alejo Martínez-Sansigre +6
Understanding the evolution of accretion activity is fundamental to our understanding of how galaxies form and evolve over the history of the Universe. We analyse a complete sample…
The Magnetic Fields at the Surface of Active Single G-K Giants
M. Aurière, R. Konstantinova-Antova, C. Charbonnel +15
We investigate the magnetic field at the surface of 48 red giants selected as promising for detection of Stokes V Zeeman signatures in their spectral lines. We use the spectropolar…
Michel Henon's first research article: An improved calculation of the perturbation of stellar velocities
Fathi Namouni
Fifteen years after the discovery of dynamical friction by Chandrasekhar, Michel Henon attempts to solve the longstanding problem of the divergence of the friction suffered by the…
Sodium and Oxygen Abundances in the Open Cluster NGC 6791 from APOGEE H-Band Spectroscopy
Katia Cunha, Verne V. Smith, Jennifer A. Johnson +27
The open cluster NGC 6791 is among the oldest, most massive and metal-rich open clusters in the Galaxy. High-resolution -band spectra from the Apache Point Observatory Galactic…
Modelling the Transfer Function for the Dark Energy Survey
C. Chang, M. T. Busha, R. H. Wechsler +40
We present a forward-modelling simulation framework designed to model the data products from the Dark Energy Survey (DES). This forward-model process can be thought of as a transfe…
The APOKASC Catalog: An Asteroseismic and Spectroscopic Joint Survey of Targets in the Kepler Fields
Marc H. Pinsonneault, Yvonne Elsworth, Courtney Epstein +42
We present the first APOKASC catalog of spectroscopic and asteroseismic properties of 1916 red giants observed in the Kepler fields. The spectroscopic parameters provided from the…
