Mapping the Galactic disk with the LAMOST and $Gaia$ Red clump sample: V: On the origin of the “young” [$α$/Fe]-enhanced stars

Posted by klaurent Peking

Kavli Affiliate: Huawei Zhang | First 5 Authors: Weixiang Sun, Yang Huang, Haifeng Wang, Chun Wang, Meng Zhang | Summary: Using a sample of nearly 140,000 primary red clump stars selected from the LAMOST and $Gaia$ surveys, we have identified a large sample of "young" [$alpha$/Fe]-enhanced stars with stellar ages younger than 6.0 Gyr and […]

Efficient calculation of carrier scattering rates from first principles

Posted by klaurent Berkeley

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Alex M. Ganose, Junsoo Park, Alireza Faghaninia, Rachel Woods-Robinson, Kristin A. Persson | Summary: The electronic transport behaviour of materials determines their suitability for technological applications. We develop an efficient method for calculating carrier scattering rates of solid-state semiconductors and insulators from first principles inputs. The […]

Small-area Population Forecast in a Segregated City using Density-Functional Fluctuation Theory

Posted by klaurent Cornell

Kavli Affiliate: Itai Cohen | First 5 Authors: Yuchao Chen, Yunus A. Kinkhabwala, Boris Barron, Matthew Hall, Tomas A. Arias | Summary: Decisions regarding housing, transportation, and resource allocation would all benefit from accurate small-area population forecasts. While various tried-and-tested forecast methods exist at regional scales, developing an accurate neighborhood-scale forecast remains a challenge partly […]

Intermediate Mass Black Hole Formation in compact Young Massive Star Clusters

Posted by klaurent Peking

Kavli Affiliate: Rainer Spurzem | First 5 Authors: Francesco Paolo Rizzuto, Thorsten Naab, Rainer Spurzem, Mirek Giersz, J. P. Ostriker | Summary: Young dense massive star clusters are a promising environment for the formation of intermediate mass black holes (IMBHs) through collisions. We present a set of 80 simulations carried out with Nbody6++GPU of 10 […]

Fresh perspective on gauging the conformal group

Posted by klaurent Cambridge

Kavli Affiliate: Anthony Lasenby | First 5 Authors: Michael Hobson, Anthony Lasenby, , , | Summary: We consider the construction of gauge theories of gravity that are invariant under local conformal transformations. We first clarify the geometric nature of global conformal transformations, in both their infinitesimal and finite forms, and the consequences of global conformal […]
