Uncertainties in the production of p nuclei in massive stars obtained from Monte Carlo variations

Rauscher, T.; Nishimura, N.; Hirschi, R.; Cescutti, G.; Murphy, A. St J.; Heger, A. (2016-12-21)

Nuclear uncertainties in the production of $p$ nuclei in massive stars have been quantified in a Monte Carlo procedure. Bespoke temperature-dependent uncertainties were assigned to different types of reactions involving ...

Simulations from chemical weather models are subject to uncertainties in the input data (e.g. emission inventory, initial and boundary conditions) as well as those intrinsic to the model (e.g. physical parameterization, ...

Systematic non-LTE study of the $-2.6 \le$ [Fe/H] $\le 0.2$ F and G dwarfs in the solar neighbourhood. II. Abundance patterns from Li to Eu

Zhao, G.; Mashonkina, L.; Yan, H. L.; Alexeeva, S.; Kobayashi, C.; Pakhomov, Yu; Shi, J. R.; Sitnova, T.; Tan, K. F.; Zhang, H. W.; Zhang, J. B.; Zhou, Z. M.; Bolte, M.; Chen, Y. Q.; Li, X.; Liu, F.; Zhai, M. (2016-12-19)

For the first time, we present an extensive study of stars with individual non-local thermodynamic equilibrium (NLTE) abundances for 17 chemical elements from Li to Eu in a sample of stars uniformly distributed over the ...

The Lockman Hole project : LOFAR observations and spectral index properties of low-frequency radio sources

Mahony, E. K.; Morganti, R.; Prandoni, I.; Bemmel, I. M. van; Shimwell, T. W.; Brienza, M.; Best, P. N.; Brüggen, M.; Rivera, G. Calistro; Gasperin, F. de; Hardcastle, M. J.; Harwood, J.

(2016-12-11)

The Lockman Hole is a well-studied extragalactic field with extensive multi-band ancillary data covering a wide range in frequency, essential for characterising the physical and evolutionary properties of the various source ...

KILOPARSEC-SCALE DUST DISKS IN HIGH-REDSHIFT LUMINOUS SUBMILLIMETER GALAXIES

Hodge, Jackie; Swinbank, Mark; Simpson, James; Smail, Ian; Walter, F.; Alexander, D.M.; Bertoldi, Frank; Biggs, Andy; Brandt, Niel; Chapman, S.C.; Coppin, Kristen; Chen, Chian Chou; Cox, Pierre; Dannerbauer, Helmut; Edge, A.

We present high-resolution (0farcs16) 870 μm Atacama Large Millimeter/submillimeter Array (ALMA) imaging of 16 luminous (${L}_{\mathrm{IR}}\sim 4\times {10}^{12}\,{L}_{\odot }$) submillimeter galaxies (SMGs) from the ALESS ...

Astrophysics: : Elemental abundances across cosmic time

Kobayashi, Chiaki (2016-12-08)

The chemical composition of a massive galaxy in the early Universe reveals an extremely short period of star formation. This result could challenge our ideas about the evolution of galaxies and of the Universe itself.

Highly variable young massive stars in ATLASGAL clumps

Kumar, M. S. N.; Contreras-Pena, C.; Lucas, P. W.; Thompson, M. A. (2016-12-05)

High-amplitude variability in Young Stellar Objects (YSOs) is usually associated with episodic accretion events. It has not been observed so far in massive YSOs. Here, the high-amplitude variable star sample of ContrerasPena ...

Time Evolution of Galaxy Scaling Relations in Cosmological Simulations

Taylor, Philip; Kobayashi, Chiaki (2016-12-01)

We predict the evolution of galaxy scaling relationships from cosmological, hydrodynamical simulations, that reproduce the scaling relations of present-day galaxies. Although we do not assume co-evolution between galaxies ...

LOFAR imaging of Cygnus A - direct detection of a turnover in the hotspot radio spectra

McKean, J. P.; Godfrey, L. E H; Vegetti, S.; Wise, Michael W.; Morganti, R.; Hardcastle, M. J.; Rafferty, D.; Avruch, I. M.; Beck, R.; Bell, M. E.; Bemmel, I. M. van; Bentum, M.

J.; Wucknitz, O.; Yatawatta, S.; Zarka, P. (2016-12-01)

The low-frequency radio spectra of the hotspots within powerful radio galaxies can provide valuable information about the physical processes operating at the site of the jet termination. These processes are responsible for ...
