Monday, although I haven't slept since Sunday.

Detection of Ks-band Thermal emission from WASP-3b
Zhao, Milburn, Barman, Hinkley, Swain, Wright, Monnier
Exoplanet secondary eclipse detected, places the orbit to be circular. Provides insight into the tidal circularization process of the star-planet system.

A large, multi-epoch H-alpha survey at z=2.23, 1.47, 0.84 & 0.40: the 11 Gyr evolution of SF galaxies from HiZELS
Sorbal, Smail, Best, Geach, Matsuda, Stott, Cirasuolo, Kurk
Ha used to trace SF activity over 0.4<z<2.23. A total of 1742, 637, 515 and 556 Ha emitters are homogeneously selected at z=0.40, 0.84, 1.47, and 2.23, respectively, and used to determine the Ha luminosity function and its evolution. The faint end slope show no evolution. L* evolves significantly. Ha evolution agrees well with other tracers of SF (FIR, UV): jointly pointing to a strong luminosity increase from z~0 to 2.2. Derive Ha SFH of the universe. Both the shape and normalization of the Ha star formation history are consistent with the measurements of the stellar mass density growth, confirming that Ha analysis traces the bulk of the formation of stars in the universe up to z~2.2. The SF activity over the last ~11 Gyrs is responsible for producing ~95% of the total stellar mass density observed locally today.
