Spectral Methods for Time-Dependent Studies of Accretion Flows. II. Two-Dimensional Hydrodynamic Disks with Self-Gravity

Chi-kwan Chan, Dimitrios Psaltis, Feryal Ozel

Spectral methods are well suited for solving hydrodynamic problems in which the self-gravity of the flow needs to be considered. Because Poisson's equation is linear, the numerical…

J/psi Photo-production at Large z in Soft Collinear Effective Theory

Sean Fleming, Adam K. Leibovich, Thomas Mehen

One of the outstanding problems in J/ψphysics is a systematic understanding of the differential photo-production cross section dsigma/dz(gamma + p -> J/psi + X), where z= E_psi/E_g…

The evolution of the star formation activity in galaxies and its dependence on environment

B. M. Poggianti, A. von der Linden, G. De Lucia +16

We study how the proportion of star-forming galaxies evolves between z=0.8 and z=0 as a function of galaxy environment, using the [OII] line in emission as a signature of ongoing s…

Bypassing the axial anomalies

D. Kekez, D. Klabucar, M. D. Scadron

Many meson processes are related to the U_A(1) axial anomaly, present in the Feynman graphs where fermion loops connect axial vertices with vector vertices. However, the coupling o…

The Effect of the Transit of Venus on ACRIM's Total Solar Irradiance Measurements: Implications for Transit Studies of Extrasolar Planets

G. Schneider, J. M. Pasachoff, R. C. Willson

We used the 8 June 2004 transit of Venus (ToV) as a surrogate to test observing methods, strategies and techniques that are being contemplated for future space missions to detect a…

Gauge Mediation from Emergent Supersymmetry

Hock-Seng Goh, Siew-Phang Ng, Nobuchika Okada

We explore the possibility of gauge mediation in a paradigm whereby supersymmetry is posited to be an accidental symmetry of Nature and the Standard Model fields are composite boun…

The Nature of Weak MgII Absorbing Structures

Nikola Milutinovic, Jane R. Rigby, Joseph R. Masiero +3

We consider geometries and possible physical models for weak low ionization absorbers based on the relative incidence of low and high ionization absorption systems. We found a tota…

A Twin Higgs Model from Left-Right Symmetry

Z. Chacko, Hock-Seng Goh, Roni Harnik

We present twin Higgs models based on the extension of the Standard Model to left-right symmetry that protect the weak scale against radiative corrections up to scales of order 5 T…

Detecting Faint Galaxies by Stacking at 24 micron

X. Z. Zheng, E. F. Bell, H. -W. Rix +4

We stack Spitzer 24 micron images for ~7000 galaxies with 0.1<z<1 in the Chandra Deep Field South to probe the thermal dust emission in low-luminosity galaxies over this redshift r…

Very Small-Scale Clustering and Merger Rate of Luminous Red Galaxies

Morad Masjedi, David W. Hogg, Richard J. Cool +8

We present the small-scale (0.01<r<8 h^{-1} Mpc) projected correlation function w_p(r_p) and real space correlation function xi(r) of 24520 luminous early-type galaxies from the Sl…

Connecting Dense Gas Tracers of Star Formation in our Galaxy to High-z Star Formation

Jingwen Wu, Neal J. Evans, Yu Gao +3

Observations have revealed prodigious amounts of star formation in starburst galaxies as traced by dust and molecular emission, even at large redshifts. Recent work shows that for…
