Descripción
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.

    Stellar halo density with LAMOST K and M giants

    Aims: We derive the morphology of the stellar component in the outer halo volume, and search for possible overdensities due to substructures therein. Methods: We made use of some of the data releases of the spectroscopic survey LAMOST DR8-DR9 in tandem with distance determinations for two subsamples, that is, of K-giants and M-giants, respectively

    Euclid preparation. XXXVI. Modelling the weak lensing angular power spectrum

    This work considers which higher order modeling effects on the cosmic shear angular power spectra must be taken into account for Euclid. We identified the relevant terms and quantified their individual and cumulative impact on the cosmological parameter inferences from Euclid. We computed the values of these higher order effects using analytic

    The discovery space of ELT-ANDES. Stars and stellar populations

    The ArmazoNes high Dispersion Echelle Spectrograph (ANDES) is the optical and near-infrared high-resolution echelle spectrograph envisioned for the Extremely Large Telescope (ELT). We present a selection of science cases, supported by new calculations and simulations, where ANDES could enable major advances in the fields of stars and stellar
