Space Telescope and Optical Reverberation Mapping Project. VIII. Time Variability of Emission and Absorption in NGC 5548 Based on Modeling the Ultraviolet Spectrum
(Astrophysical Journal, 2019-08-20)
We model the ultraviolet spectra of the Seyfert 1 galaxy NGC 5548 obtained with the Hubble Space Telescope during the 6 month reverberation mapping campaign in 2014. Our model of the emission from NGC 5548 corrects for ...
16TH INTERNATIONAL SYMPOSIUM ON CAPTURE GAMMA-RAY SPECTROSCOPY AND RELATED TOPICS (CGS16)
(16TH Internatinal Symposium on Capture Gamma-Ray Spectroscopy and Related Topics (CGS16), 2018)
The paper reviews the systematic studies of triaxial deformations, new mode excitations and shape evolutions with regard to triaxial deformation in the neutron-rich nuclei with Z = 41-46, A similar to 100-116.
H-band discovery of additional second-generation stars in the Galactic bulge globular cluster NGC 6522 as observed by APOGEE and Gaia
(ASTRONOMY & ASTROPHYSICS, 2019-07-22)
We present an elemental abundance analysis of high-resolution spectra for five giant stars spatially located within the innermost regions of the bulge globular cluster NGC 6522 and derive Fe, Mg, Al, C, N, O, Si, and Ce ...
An embedding technique to determine tau tau backgrounds in proton-proton collision data
(Journal of Instrumentation, 2019-06)
An embedding technique is presented to estimate standard model tau tau backgrounds from data with minimal simulation input. In the data, the muons are removed from reconstructed mu mu events and replaced with simulated tau ...
A search for pair production of new light bosons decaying into muons in proton-proton collisions at 13 TeV
(Physics Letters B, 2019-09-10)
A search for new light bosons decaying into muon pairs is presented using a data sample corresponding to an integrated luminosity of 35.9 fb(-1) of proton-proton collisions at a center-of-mass energy root s = 13 TeV, ...
Search for vectorlike leptons in multilepton final states in proton-proton collisions at root s=13 TeV
(Physical Review D, 2019-09-06)
A search for vectorlike leptons in multilepton final states is presented. The data sample corresponds to an integrated luminosity of 77.4 fb(-1) of proton-proton collisions at a center-of-mass energy of 13 TeV collected ...
Dark Matter benchmark models for early LHC Run-2 Searches: Report of the ATLAS/CMS Dark Matter Forum
(Physics of the Dark Universe, 2020-01)
This document is the final report of the ATLAS-CMS Dark Matter Forum, a forum organized by the ATLAS and CMS collaborations with the participation of experts on theories of Dark Matter, to select a minimal basis set of ...
A Low-mass Pre-main-sequence Eclipsing Binary in Lower Centaurus Crux Discovered with TESS
(The Astrophysical Journal, 2022-12-20)
We report the discovery of 2M1222-57 as a low-mass, pre-main-sequence (PMS) eclipsing binary (EB) in the Lower Centaurus Crux (LCC) association for which, using Gaia parallaxes and proper motions with a neural net age ...
Backscattering and Line Broadening in Orion
(Astronomical Journal, 2022-12-19)
Examination of emission lines in high-velocity-resolution optical spectra of the Orion Nebula confirms that the velocity component on the red wing of the main ionization front emission line is due to backscattering in the ...
Real-time real-space density functional theory calculations of electron scattering in materials
(Vanderbilt University. Dept. of Physics and Astronomy, 2012-05-04)
Density functional theory is utilized in real-time,
real-space simulations of LEED measurements and attosecond electron
scattering. For LEED measurements, we find that our simulation results
agree well with experimental ...
