    Constraints on an Optical Afterglow and on Supernova Light Following the Short Burst GRB 050813
    We report early follow-up observations of the error box of the short burst GRB 050813 using the telescopes at Calar Alto and Observatorio Sierra Nevada...

    Constraints on anomalous Higgs boson couplings using production and decay information in the four-lepton final state
    A search is performed for anomalous interactions of the recently discovered Higgs boson using matrix element techniques with the information from its decay to...

    Constraints on axion-like particles with the Perseus Galaxy Cluster with MAGIC
    Axion-like particles (ALPs) are pseudo-Nambu-Goldstone bosons that emerge in various theories beyond the standard model. These particles can interact with high...

    Constraints on Circumstellar Material around the Type Ia Supernova 2007af
    Patat et al. recently inferred the existence of circumstellar material around a normal Type Ia supernova (SN Ia) for the first time, finding time-variable Na I...

    Constraints on cosmological parameters from recent measurements of cosmic microwave background anisotropy
    We present new results from a study of recent cosmic microwave background (CMB) observations which provide the first strong evidence for the existence of a...

    Constraints on dark matter to dark radiation conversion in the late universe with DES-Y1 and external data
    We study a phenomenological class of models where dark matter converts to dark radiation in the low redshift epoch. This class of models, dubbed DMDR...

    Constraints on Feedback Processes during the Formation of Early-type Galaxies
    Galaxies are found to obey scaling relations between a number of observables. These relations follow different trends at the low- and high-mass ends. The...

    Constraints on Gamma-Ray and Neutrino Emission from NGC 1068 with the MAGIC Telescopes
    Starburst galaxies and star-forming active galactic nuclei are among the candidate sources thought to contribute appreciably to the extragalactic gamma-ray and...

    Constraints on Jupiters from observations of Galactic bulge microlensing events during 2000
    We present observations of eight Galactic bulge microlensing events taken with the 1.0-m Jacobus Kapteyn Telescope (JKT) on La Palma during 2000 June and July...
