A Mid-Infrared Study of the Class 0 Cluster in LDN 1448
J. C. O'Linger, D. M. Cole, M. E. Ressler +1
We present ground-based mid-infrared observations of Class 0 protostars in LDN 1448. Of the five known protostars in this cloud, we detected two, L1448N:A and L1448C, at 12.5, 17.9…
A Predictive Theory of Games
David H. Wolpert
Conventional noncooperative game theory hypothesizes that the joint strategy of a set of players in a game must satisfy an "equilibrium concept". All other joint strategies are con…
The Study of the Pioneer Anomaly: New Data and Objectives for New Investigation
Slava G. Turyshev, Viktor T. Toth, Larry R. Kellogg +2
Radiometric tracking data from Pioneer 10 and 11 spacecraft has consistently indicated the presence of a small, anomalous, Doppler frequency drift, uniformly changing with a rate o…
Deep Photometry of Andromeda Reveals Striking Similarities in the Tidal Stream and Spheroid Populations
Thomas M. Brown, Ed Smith, Puragra Guhathakurta +5
We present a color-magnitude diagram (CMD) for a field in the giant tidal stream of the Andromeda galaxy (M31). These observations, taken with the Advanced Camera for Surveys on th…
An origin for short g-ray bursts unassociated with current star formation
S. D. Barthelmy, G. Chincarini, D. N. Burrows +28
Two short (<2 s) g-ray bursts (GRBs) have recently been localized and fading afterglow counterparts detected. The combination of these two results left unclear the nature of the ho…
Measurement of the Spatial Cross-Correlation Function of Damped Lyman Alpha Systems and Lyman Break Galaxies
J. Cooke, A. M. Wolfe, E. Gawiser +1
We present the first spectroscopic measurement of the spatial cross-correlation function between damped Lyman alpha systems (DLAs) and Lyman break galaxies (LBGs). We obtained deep…
