Aims: The standard method of searching parameter space for transits is ill-suited to data sets with long time baselines and poor temporal coverage, such as that anticipated from Gaia. In this paper, we present an alternative method for identifying transit candidates is such data, one focusing on finding periodicity in high S/N outliers. Methods: We

Although the spectral lines of hydrogen contain valuable information on the physical properties of a variety of astrophysical plasmas, including the upper solar chromosphere, relatively little is known about their scattering polarization signals, whose modification via the Hanle effect may be exploited for magnetic field diagnostics. Here we report

We report on the redshift measurement and CO line excitation of HERMES J105751.1+573027 (HLSW-01), a strongly lensed submillimeter galaxy discovered in Herschel/SPIRE observations as part of the Herschel Multi-tiered Extragalactic Survey (HerMES). HLSW-01 is an ultra-luminous galaxy with an intrinsic far-infrared luminosity of L FIR = 1.4 × 1013 L

We report a rebrightening of the newly discovered transient MAXI J0556-332 (ATEL #3102, #3103, #3104, #3106, #3110, #3112, #3116, #3119) in optical through soft-X-ray wavelengths. The source is being monitored regularly in the I-band using the SMARTS 1.3m telescope in CTIO, and the I-band light curve has been showing a monotonically increasing

Spectroscopic observations were obtained with FLAMES+GIRAFFE at the ESO 8-meter VLT telescope. FLAMES is a fiber multi-object spectrograph, allowing the simultaneous observation of up to 130 objects. For each configuration five separate 3200s exposures were obtained on different night from November 2007 to March 2008. (2 data files).
