A mature galaxy cluster at z=1.58 around the radio galaxy 7C1753+6311
E. A. Cooke, N. A. Hatch, D. Stern +9
We report on the discovery of a z=1.58 mature cluster around the high-redshift radio galaxy 7C1753+6311, first identified in the Clusters Around Radio-Loud AGN survey. Two-thirds o…
A Bootstrap Multigrid Eigensolver
James Brannick, Shuhao Cao
This paper introduces bootstrap multigrid methods for solving eigenvalue problems arising from the discretization of partial differential equations. Inspired by the full bootstrap…
Probing star formation in the dense environments of z~1 lensing halos aligned with dusty star-forming galaxies detected with the South Pole Telescope
N. Welikala, M. Béthermin, D. Guery +46
We probe star formation in the environments of massive dark matter halos at redshifts of . This star formation is linked to a sub-millimetre cl…
Are Compton-Thick AGN the Missing Link Between Mergers and Black Hole Growth?
Dale D. Kocevski, Murray Brightman, Kirpal Nandra +12
We examine the host morphologies of heavily obscured active galactic nuclei (AGN) at to test whether obscured supermassive black hole growth at this epoch is preferentiall…
Mapping the Galaxy Color-Redshift Relation: Optimal Photometric Redshift Calibration Strategies for Cosmology Surveys
Daniel Masters, Peter Capak, Daniel Stern +17
Calibrating the photometric redshifts of >10^9 galaxies for upcoming weak lensing cosmology experiments is a major challenge for the astrophysics community. The path to obtaining t…
Anisotropic mesh adaptation for 3D anisotropic diffusion problems with application to fractured reservoir simulation
Xianping Li, Weizhang Huang
Anisotropic mesh adaptation is studied for linear finite element solution of 3D anisotropic diffusion problems. The M-uniform mesh approach is used, where an anisotropic adaptive m…
Quasar Variability in the Mid-Infrared
Szymon Kozlowski, Christopher S. Kochanek, Matthew L. N. Ashby +5
The Decadal IRAC Bootes Survey is a mid-IR variability survey of the ~9 sq. deg. of the NDWFS Bootes Field and extends the time baseline of its predecessor, the Spitzer Deep, Wide-…
Multilayer Layer Graphene Nanoribbon Flash Memory: Analysis of Programming and Erasing Operation
Nahid M. Hossain, Md Belayat Hossain, Masud H. Chowdhury
Flash memory based on floating gate transistor is the most widely used memory technology in modern microelectronic applications. We recently proposed a new concept of multilayer gr…
Analysis of radiation effect on the threshold voltage of flash memory device
Nahid M. Hossain, Jitendra Koppu, Masud H Chowdhury
Flash memory experiences adverse effects due to radiation. These effects can be raised in terms of doping, feature size, supply voltages, layout, shielding. The the operating point…
Multilayer Graphene Nanoribbon and Carbon Nanotube based Floating Gate Transistor for Nonvolatile Flash Memory
Nahid M. Hossain, Masud H. Chowdhury
Floating gate transistor is the basic building block of non-volatile flash memory, which is one of the most widely used memory gadgets in modern micro and nano electronic applicati…
Lebesgue Constants Arising in a Class of Collocation Methods
William W. Hager, Hongyan Hou, Anil V. Rao
Estimates are obtained for the Lebesgue constants associated with the Gauss quadrature points on augmented by the point and with the Radau quadrature points on eith…
The formation history of massive cluster galaxies as revealed by CARLA
E. A. Cooke, N. A. Hatch, A. Rettura +12
We use a sample of 37 of the densest clusters and protoclusters across from the Clusters Around Radio-Loud AGN (CARLA) survey to study the formation of massive…
Gapped Surface States in a Strong-Topological-Semimetal
A. P. Weber, Q. D. Gibson, Huiwen Ji +4
A three-dimensional strong-topological-insulator or -semimetal hosts topological surface states which are often said to be gapless so long as time-reversal symmetry is preserved. T…
Tracing kinematic (mis)alignments in CALIFA merging galaxies: Stellar and ionized gas kinematic orientations at every merger stage
J. K. Barrera-Ballesteros, B. García-Lorenzo, J. Falcón-Barroso +27
We present spatially resolved stellar and/or ionized gas kinematic properties for a sample of 103 interacting galaxies, tracing all merger stages: close companions, pairs with morp…
Testing the Modern Merger Hypothesis via the Assembly of Massive Blue Elliptical Galaxies in the Local Universe
Tim Haines, D. H. McIntosh, S. F. Sánchez +2
The modern merger hypothesis offers a method of forming a new elliptical galaxy through merging two equal-mass, gas-rich disk galaxies fuelling a nuclear starburst followed by effi…
Mid-infrared luminous quasars in the GOODS-Herschel fields: a large population of heavily-obscured, Compton-thick quasars at z~2
