Description
A new series of observation of the Crab Nebula in TeV gamma rays using an improved camera on the Whipple Observatory 10 m Optical Reflector is reported. The smaller pixel size results in a lower energy threshold for gamma-ray detection than that reported in WEA89. The improvement in SNR compared with the original camera (Cawley et al., 1990) is a factor of three to four. The results reported here confirm all the salient features of the detection reported in WEA89, and the significantly deeper detection now permits the energy spectrum to be derived. It is also possible to optimize the detection technique so that sources whose intensity is one-tenth that of the Crab can be detected in 60 hrs of observation.

    An ultra-short-period super-Earth with an extremely high density and an outer companion
    We present the discovery and characterization of a new multi-planetary system around the Sun-like star K2-360 (EPIC 201595106). K2-360 was first identified in K2 photometry as the host of an ultra-short-period (USP) planet candidate with a period of 0.88 d. We obtained follow-up transit photometry, confirming the star as the host of the signal

    Neural calibration of imaging Stokes polarimeters
    Current polarimetric calibration techniques derive the instrument modulation matrix by numerically fitting an instrumental model to measurements of a set of calibration Stokes vectors. These techniques are typically limited to an error on the retrieved normalized Stokes Q, U and V parameters, in the $1\times10^{-2}$ to $1\times10^{-3}$ range. This

    Model-based identification of solar coronal mass ejections using deep neural networks
    Coronal mass ejections (CMEs) are a major driver of space weather and thus can have important negative technological and social impacts. To assess their geoeffectiveness once they are ejected, it is crucial their prompt identification in coronagraph images. In the last decade, deep neural networks (DNN) have experienced enormous improvements in
