Broad absorption line quasars have the same cool dust emission as quasars without BALs
The results of a sub-millimeter survey of SDSS broad CIV absorption line quasars is discussed. It is found that the

Composite fermions in quantum Hall systems
The occurrence of incompressible quantum fluid states of a two dimensional system is a result of electron--electron interactions in a

HCN in the inner envelope of {chi} Cygni
We have detected the (0,11c,0)J=3-2 and (0,0,0)J=8-7 transitions of HCN towards the S star {chi} Cygni. The excitation requirements of

Massive star populations in I Zw 18: A probe of stellar evolution in the early universe
We present a study of the gaseous and stellar emission in I Zw18, the most metal-poor star-forming galaxy known. Archival

Mid-UV Determination of Elliptical Galaxy Abundances and Ages
We investigate the effects of abundance and age on the mid-UV spectra and Mg_{2} strengths of stellar populations using simple

Partition function zeros at first-order phase transitions: A general analysis
We present a general, rigorous theory of partition function zeros for lattice spin models depending on one complex parameter. First,

Partition function zeros at first-order phase transitions: Pirogov-Sinai theory
This paper is a continuation of our previous analysis [BBCKK] of partition functions zeros in models with first-order phase transitions

Proof of the local REM conjecture for number partitioning I: Constant energy scales
The number partitioning problem is a classic problem of combinatorial optimization in which a set of $n$ numbers is partitioned

Proof of the local REM conjecture for number partitioning II: growing energy scales
We continue our analysis of the number partitioning problem with $n$ weights chosen i.i.d. from some fixed probability distribution with

Quantitative Fluorescence Excitation Spectra for Synthetic Eumelanin
Previously reported excitation spectra for eumelanin are sparse and inconsistent. Moreover, these studies have failed to account for probe beam

Self-Repairing Peer-to-Peer Networks
In this paper we study the resilience of peer-to-peer networks to preferential attacks. We define a network model and experiment

Spontaneous Inflation and the Origin of the Arrow of Time
We suggest that spontaneous eternal inflation can provide a natural explanation for the thermodynamic arrow of time, and discuss the
