    Chandra Observations of the X-Ray Jet of 3C 273
    We report results from Chandra observations of the X-ray jet of 3C 273 during the calibration phase in 2000 January. The zeroth-order images and spectra from...

    Changes in Earth's Reflectance over the Past Two Decades
    We correlate an overlapping period of earthshine measurements of Earth's reflectance (from 1999 through mid-2001) with satellite observations of global cloud...

    Changing Look of the Optical Spectrum of the MeV Blazar PKS 0446+112 (4FGL J0449.1+1121)
    Following the high activity of the γ-ray Fermi source 4FGL J0449.1+1121 (PKS 0446+112), possibly associated with a IceCube neutrino event IC-240105A, we...

    Changing-look Active Galactic Nuclei from the Dark Energy Spectroscopic Instrument. IV. Broad Emission-line Evolution Sequence among Hα, Mg II, and Hβ
    From a parent catalog of 561 changing-look active galactic nuclei (CL-AGNs) identified by W.-J. Guo et al., we investigate the evolutionary sequence of broad...

    Channeling 5 Minute Photospheric Oscillations into the Solar Outer Atmosphere through Small-Scale Vertical Magnetic Flux Tubes
    We report two-dimensional MHD simulations which demonstrate that photospheric 5 minute oscillations can leak into the chromosphere inside small-scale vertical...

    Chaotic Behaviour of the Temporal Evolution of Star Formation Rate in the Solar Neighborhood
    We use statistical data giving the number of stars formed as a function of the age, assigned using the observed deterministic relation between chromospheric...

    Chaotic scalar fields as models for dark energy
    We consider stochastically quantized self-interacting scalar fields as suitable models to generate dark energy in the Universe. Second quantization effects lead...

    Characterisation at Cryogenic Temperatures of an Attenuator for an Application of Astrophysical Instrumentation with MKIDs
    The use of non-cryogenic certified commercial electronics for cryogenic applications may be attractive due to their cost and availability, but it also carries...
