The chemical compositions of 10 new sub-DLAs and strong Lyman-limit systems at z < 1.5
Joseph D. Meiring, Varsha P. Kulkarni, James T. Lauroesch +4
We present chemical abundance measurements from medium resolution observations of 8 sub-damped Lyman-alpha absorber and 2 strong Lyman-limit systems at z < 1.5 observed with the MI…
Modeling The Structure And Dynamics of Dwarf Spheroidal Galaxies with Dark Matter And Tides
Ricardo R. Munoz, Steven R. Majewski, Kathryn V. Johnston
We report the results of N-body simulations of disrupting satellites aimed at exploring whether the observed features of dSphs can be accounted for with simple, mass-follows-light…
A Search for Extended Ultraviolet Disk (XUV-disk) Galaxies in the Local Universe
David A. Thilker, Luciana Bianchi, Gerhardt Meurer +26
We have initiated a search for extended ultraviolet disk (XUV-disk) galaxies in the local universe. Herein, we compare GALEX UV and visible--NIR images of 189 nearby (D40 Mpc) S…
Luminosity Dependent X-ray AGN Clustering ?
M. Plionis, M. Rovilos, S. Basilakos +2
We have analysed the angular clustering of X-ray selected active galactic nuclei (AGN) in different flux-limited sub-samples of the Chandra Deep Field North (CDF-N) and South (CDF-…
Ultraviolet, Optical, and Infrared Constraints on Models of Stellar Populations and Dust Attenuation
Benjamin D. Johnson, David Schiminovich, Mark Seibert +19
The color of galaxies is a fundamental property, easily measured, that constrains models of galaxies and their evolution. Dust attenuation and star formation history (SFH) are the…
Gravitational Waves From the End of Inflation: Computational Strategies
Richard Easther, John T. Giblin, Eugene A. Lim
Parametric resonance or preheating is a plausible mechanism for bringing about the transition between the inflationary phase and a hot, radiation dominated universe. This epoch res…
Pre-Merger Localization of Gravitational-Wave Standard Sirens With LISA: Triggered Search for an Electromagnetic Counterpart
Bence Kocsis, Zoltan Haiman, Kristen Menou
Electromagnetic (EM) counterparts to supermassive black hole binary mergers observed by LISA can be localized to within the field of view of astronomical instruments ~10 deg^2 hour…
UV/Optical Detections of Candidate Tidal Disruption Events by GALEX and CFHTLS
S. Gezari, S. Basa, D. C. Martin +11
We present two luminous UV/optical flares from the nuclei of apparently inactive early-type galaxies at z=0.37 and 0.33 that have the radiative properties of a flare from the tidal…
On Signatures of Atmospheric Features in Thermal Phase Curves of Hot Jupiters
Emily Rauscher, Kristen Menou, James Y-K. Cho +2
Turbulence is ubiquitous in Solar System planetary atmospheres. In hot Jupiter atmospheres, the combination of moderately slow rotation and thick pressure scale height may result i…
The UV-Optical Color Magnitude Diagram II: Physical Properties and Morphological Evolution On and Off of a Star-Forming Sequence
David Schiminovich, Ted K. Wyder, D. Christopher Martin +23
We use the UV-optical color magnitude diagram in combination with spectroscopic and photometric measurements derived from the SDSS spectroscopic sample to measure the distribution…
Implications for the Origin of GRB 070201 from LIGO Observations
LIGO Scientific Collaboration, K. Hurley
We analyzed the available LIGO data coincident with GRB 070201, a short duration hard spectrum gamma-ray burst whose electromagnetically determined sky position is coincident with…
Echo Emission From Dust Scattering and X-Ray Afterglows of Gamma-Ray Bursts
L. Shao, Z. G. Dai, N. Mirabal
We investigate the effect of X-ray echo emission in gamma-ray bursts (GRBs). We find that the echo emission can provide an alternative way of understanding X-ray shallow decays and…
Outburst of the 2 s Anomalous X-ray Pulsar 1E 1547.0-5408
J. P. Halpern, E. V. Gotthelf, J. Reynolds +2
Following our discovery of radio pulsations from the newly recognized Anomalous X-ray Pulsar (AXP) 1E 1547.0-5408, we initiated X-ray monitoring with the Swift X-ray Telescope, and…
Metal Absorption Systems in Spectra of Pairs of QSOs
David Tytler, Mark Gleed, Carl Melis +6
We present the first large sample of absorption systems in paired QSOs consisting of 691 absorption systems in the spectra of 310 QSOs including 170 pairings. All these absorption…
Deep-Survey Constraints on X-ray Outbursts from Galactic Nuclei
B. Luo, W. N. Brandt, A. T. Steffen +1
Luminous X-ray outbursts with variability amplitudes as high as ~1000 have been detected from a small number of galactic nuclei. These events are likely associated with transient f…
Eight new MSPs in NGC 6440 and NGC 6441
Paulo C. C. Freire, Scott M. Ransom, Steve Begin +4
We report the discovery of five new millisecond pulsars in the globular cluster NGC 6440 and three new ones in NGC 6441; each cluster has one previously known pulsar. Four of the n…
CCO Pulsars as Anti-Magnetars: Evidence of Neutron Stars Weakly Magnetized at Birth
E. V. Gotthelf, J. P. Halpern
Our new study of the two central compact object pulsars, PSR J1210-5226 (P = 424 ms) and PSR J1852+0040 (P = 105 ms), leads us to conclude that a weak natal magnetic field shaped t…
