Linhua Jiang, Yue Shen, Ian D. McGreer +3
We present a reverberation mapping (RM) experiment that combines broad- and intermediate-band photometry; it is the first such attempt targeting a sample of 13 quasars at $0.2<z<0.…
MApping the Most Massive Overdensities Through Hydrogen (MAMMOTH) I: Methodology
Zheng Cai, Xiaohui Fan, Sebastien Peirani +8
Modern cosmology predicts that a galaxy overdensity is associated to a large reservoir of the intergalactic gas, which can be traced by the Ly forest absorption. We have underta…
Spectral principal component analysis of mid-infrared spectra of a sample of PG QSOs
Wei-Hao Bian, Zhi-Cheng He, Richard Green +3
A spectral principal component analysis (SPCA) of a sample of 87 PG QSOs at is presented for their mid-infrared spectra from Spitzer Space Telescope. We have derived the…
Cross-field transport in Goldreich-Sridhar MHD turbulence
F. Fraschetti
I derive analytically the temporal dependence of the perpendicular transport coefficient of a charged particle in the three-dimensional anisotropic turbulence conjectured by Goldre…
Planetesimals in Debris Disks
Andrew N. Youdin, George H. Rieke
Planetesimals form in gas-rich protoplanetary disks around young stars. However, protoplanetary disks fade in about 10 Myr. The planetesimals (and also many of the planets) left be…
An M Dwarf Companion and Its Induced Spiral Arms in the HD 100453 Protoplanetary Disk
Ruobing Dong, Zhaohuan Zhu, Jeffrey Fung +3
Recent VLT/SPHERE near-infrared imaging observations revealed two spiral arms with a near m=2 rotational symmetry in the protoplanetary disk around the ~1.7 solar mass Herbig star…
Towards 21st Century Stellar Models: Star Clusters, Supercomputing, and Asteroseismology
S. W. Campbell, T. N. Constantino, V. D'Orazi +8
Stellar models provide a vital basis for many aspects of astronomy and astrophysics. Recent advances in observational astronomy -- through asteroseismology, precision photometry, h…
CLASH-VLT: A Highly Precise Strong Lensing Model of the Galaxy Cluster RXC J2248.7-4431 (Abell S1063) and Prospects for Cosmography
G. B. Caminha, C. Grillo, P. Rosati +32
We perform a comprehensive study of the total mass distribution of the galaxy cluster RXCJ2248 () with a set of high-precision strong lensing models, which take advantage…
Cross-correlation of gravitational lensing from DES Science Verification data with SPT and Planck lensing
D. Kirk, Y. Omori, A. Benoit-Lévy +89
We measure the cross-correlation between weak lensing of galaxy images and of the cosmic microwave background (CMB). The effects of gravitational lensing on different sources will…
A continuum from clear to cloudy hot-Jupiter exoplanets without primordial water depletion
David K. Sing, Jonathan J. Fortney, Nikolay Nikolov +18
Thousands of transiting exoplanets have been discovered, but spectral analysis of their atmospheres has so far been dominated by a small number of exoplanets and data spanning rela…
Magellan/M2FS Spectroscopy of Tucana 2 and Grus 1
Matthew G. Walker, Mario Mateo, Edward W. Olszewski +8
We present results from spectroscopic observations with the Michigan/Magellan Fiber System (M2FS) of stellar targets along the line of sight to the newly-discovered `ultrafai…
The Inner Debris Structure in the Fomalhaut Planetary System
Kate Y. L. Su, George H. Rieke, Denis Defrere +5
Fomalhaut plays an important role in the study of debris disks and small bodies in other planetary systems. The proximity and luminosity of the star make key features of its debris…
Orbital Architectures of Planet-Hosting Binaries: I. Forming Five Small Planets in the Truncated Disk of Kepler-444A
Trent J. Dupuy, Kaitlin M. Kratter, Adam L. Kraus +5
We present the first results from our Keck program investigating the orbital architectures of planet-hosting multiple star systems. Kepler-444 is a metal-poor triple star system th…
