The case for inflow of the broad-line region of active galactic nuclei

C. Martin Gaskell, Rene W. Goosmann

The high-ionization lines of the broad-line region (BLR) of thermal active galactic nuclei (AGNs) show blueshifts of a few hundred km/s to several thousand km/sec with respect to t…

Neptune's Dynamic Atmosphere from Kepler K2 Observations: Implications for Brown Dwarf Light Curve Analyses

Amy A. Simon, Jason F. Rowe, Patrick Gaulme +9

Observations of Neptune with the Kepler Space Telescope yield a 49-day light curve with 98% coverage at a 1-minute cadence. A significant signature in the light curve comes from di…

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 $α$ forest absorption. We have underta…

Satellite accretion in action: a tidally disrupting dwarf spheroidal around the nearby spiral galaxy NGC 253

Aaron J. Romanowsky, D. Martinez-Delgado, Nicolas F. Martin +7

We report the discovery of NGC 253-dw2, a dwarf spheroidal (dSph) galaxy candidate undergoing tidal disruption around a nearby spiral galaxy, NGC 253 in the Sculptor group: the fir…

The SLUGGS Survey: stellar kinematics, kinemetry and trends at large radii in 25 early-type galaxies

Caroline Foster, Nicola Pastorello, Joel Roediger +9

Due to longer dynamical timescales, the outskirts of early-type galaxies retain the footprint of their formation and assembly. Under the popular two-phase galaxy formation scenario…

A simple phenomenological model for describing the normal state single particle spectral function of high temperature superconductors

Kazue Matsuyama, Rohit Dilip, G. -H. Gweon

Describing the normal state single particle spectral function line shapes of high temperature superconductors remains an important goal in condensed matter physics. Recently, we ha…

Kinematics and Angular Momentum in Early Type Galaxy Halos

Jean P. Brodie, Aaron Romanowsky, the SLUGGS team

We use the kinematics of discrete tracers, primarily globular clusters (GCs) and planetary nebulae (PNe), along with measurements of the integrated starlight to explore the assembl…

Gamma rays from the quasar PKS 1441+25: story of an escape

A. U. Abeysekara, S. Archambault, A. Archer +103

Outbursts from gamma-ray quasars provide insights on the relativistic jets of active galactic nuclei and constraints on the diffuse radiation fields that fill the Universe. The det…

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…

The Bright Symbiotic Mira EF Aquilae

Bruce Margon, J. Xavier Prochaska, Nicolas Tejos +1

An incidental spectrum of the poorly studied long period variable EF Aquilae shows [O III] emission indicative of a symbiotic star. Strong GALEX detections in the UV reinforce this…

A tidally disrupting dwarf galaxy in the halo of NGC 253

Elisa Toloba, David Sand, Kristine Spekkens +7

We report the discovery of Scl-MM-Dw2, a new dwarf galaxy at a projected separation of $\sim$ 50 kpc from NGC 253, as part of the PISCeS (Panoramic Imaging Survey of Centaurus and S…

Time-dependent analysis of $B^{0} \to K_{S}^{0} π^{-} π^{+} γ$ decays and studies of the $K^{+} π^{-} π^{+}$ system in $B^{+} \to K^{+} π^{-} π^{+} γ$ decays

P. del Amo Sanchez, others

We measure the time-dependent $C P$ asymmetry in the radiative-penguin decay $B^{0} \to K_{S}^{0} π^{-} π^{+} γ$ , using a sample of $471$ million $Υ(4S) \to B{\kern 0.18em\overline{\kern…

Infrared color selection of massive galaxies at z > 3

T. Wang, D. Elbaz, C. Schreiber +29

We introduce a new color-selection technique to identify high-redshift, massive galaxies that are systematically missed by Lyman-break selection. The new selection is based on the…

Growing massive black holes through super-critical accretion of stellar-mass seeds

A. Lupi, F. Haardt, M. Dotti +3

The rapid assembly of the massive black holes that power the luminous quasars observed at $z \sim 6 - 7$ remains a puzzle. Various direct collapse models have been proposed to head-s…

The time-dependent Aharonov-Casher effect

Douglas Singleton, Jaryd Ulbricht

In this paper we give a covariant expression for Aharonov-Casher phase. This expression is a combination of the canonical electric field, Aharonov-Casher phase plus a magnetic fiel…
