    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...
  • Publication
    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...
  • Publication
    Constraints on Lorentz invariance violation from the extraordinary Mrk 421 flare of 2014 using a novel analysis method
    The Lorentz Invariance Violation (LIV), a proposed consequence of certain quantum gravity (QG) scenarios, could instigate an energy-dependent group velocity for...

    Constraints on particle acceleration in SS433/W50 from MAGIC and H.E.S.S. observations
    Context. The large jet kinetic power and non-thermal processes occurring in the microquasar SS 433 make this source a good candidate for a very high-energy (VHE...

    Constraints on primordial magnetic fields from their impact on the ionization history with Planck 2018
    We update and extend our previous cosmic microwave background anisotropy constraints on primordial magnetic fields through their dissipation by ambipolar...
  • Publication
    Constraints on redshifts of blazars from extragalactic background light attenuation using Fermi-LAT data
    The extragalactic high-energy γ-ray sky is dominated by blazars, which are active galactic nuclei with their jets pointing towards us. Distance measurements are...

    Constraints on spinning dust towards Galactic targets with the Very Small Array: a tentative detection of excess microwave emission towards 3C396
    We present results from observations made at 33 GHz with the Very Small Array (VSA) telescope towards potential candidates in the Galactic plane for spinning...
  • Publication
    Constraints on the Abundance of Primordial Black Holes from X-Ray Quasar Microlensing Observations: Substellar to Planetary Mass Range
    We use X-ray observations of quasar microlensing (sensitive to smaller compact objects than in the optical) to study the possible presence of a population of...
