The High-z Quasar Hubble Diagram

Fulvio Melia

Two recent discoveries have made it possible for us to begin using high-z quasars as standard candles to construct a Hubble Diagram (HD) at z > 6. These are (1) the recognition fro…

Brown Dwarf Photospheres are Patchy: A Hubble Space Telescope Near-infrared Spectroscopic Survey Finds Frequent Low-level Variability

Esther Buenzli, Daniel Apai, Jacqueline Radigan +2

Condensate clouds strongly impact the spectra of brown dwarfs and exoplanets. Recent discoveries of variable L/T transition dwarfs argued for patchy clouds in at least some ultraco…

A Refined Waring Problem for Finite Simple Groups

Michael Larsen, Pham Huu Tiep

Let v and w be nontrivial words in two free groups. We prove that, for all sufficiently large finite non-abelian simple groups G, there exist subsets C of v(G) and D of w(G) of siz…

Three-dimensional light-matter interface for collective spin squeezing in atomic ensembles

Ben Q. Baragiola, Leigh M. Norris, Enrique Montano +3

We study the three-dimensional nature of the quantum interface between an ensemble of cold, trapped atomic spins and a paraxial laser beam, coupled through a dispersive interaction…

WFIRST Science with a Probe Class Mission

Rodger Thompson, James Green, George Rieke +7

WFIRST is the highest priority space mission of the Decadal review, however, it is unlikely to begin in this decade primarily due to a anticipated NASA budget that is unlikely to h…

Universal Labeling Algebras as Invariants of Layered Graphs

Susan Durst

In this work we will study the universal labeling algebra A(Gamma), a related algebra B(Gamma), and their behavior as invariants of layered graphs. We will introduce the notion of…

Mechanically Detecting and Avoiding the Quantum Fluctuations of a Microwave Field

J. Suh, A. J. Weinstein, C. U. Lei +5

During the theoretical investigation of the ultimate sensitivity of gravitational wave detectors through the 1970's and '80's, it was debated whether quantum fluctuations of the li…

A novel terahertz time-domain spectroscopic endoscope based on a single photoconductive antenna chip

Jitao Zhang

The common terahertz time-domain spectroscopy (THz-TDS) based on photoconductive antenna (PCA) needs two separate PCA chips. One PCA works as an emitter, and the other works as a r…

The Type IIb Supernova 2013df and Its Cool Supergiant Progenitor

Schuyler D. Van Dyk, WeiKang Zheng, Ori D. Fox +10

We have obtained early-time photometry and spectroscopy of Supernova (SN) 2013df in NGC 4414. The SN is clearly of Type IIb, with notable similarities to SN 1993J. From its luminos…
