LIGHTS: A robust technique to identify galaxy edges
The LIGHTS survey is imaging galaxies at a depth and spatial resolution comparable to what the Legacy Survey of Space and Time (LSST) will produce in 10 years...
Likely optical counterpart of the cool middle-aged pulsar J1957+5033
The 840-kyr-old pulsar PSR J1957+5033, detected so far only in γ- and X-rays, is a nearby and rather cool neutron star with a temperature of 0.2-0.3 MK, a...
Limitations of the Ca II 8542 Å Line for the Determination of Magnetic Field Oscillations
Chromospheric umbral oscillations produce periodic brightenings in the core of some spectral lines, known as umbral flashes. They are also accompanied by...
Limited impact of jet-induced feedback in the multi-phase nuclear interstellar medium of 4C12.50
Context. 4C12.50 (IRAS 13451+1232) at z = 0.122 is an ultraluminous infared radio galaxy that has often been proposed as a prime candidate for the link between...
Limiting the Abundance of LIGO/Virgo Black Holes with Microlensing Observations of Quasars of Finite Size
We present a simple but general argument that strongly limits the abundance of primordial black holes (PBHs) (or other unknown population of compact objects)...
Limits on Hot Intracluster Gas Contributions to the Tenerife Temperature Anisotropy Map
We limit the contribution of the hot intracluster gas, by means of the Sunyaev-Zeldovich effect, to the temperature anisotropies measured by the Tenerife...
Limits on Light-Speed Anisotropies from Compton Scattering of High-Energy Electrons
The possibility of anisotropies in the speed of light relative to the limiting speed of electrons is considered. The absence of sidereal variations in the...
Limits on the flux of tau neutrinos from 1 PeV to 3 EeV with the MAGIC telescopes
A search for tau neutrino induced showers with the MAGIC telescopes is presented. The MAGIC telescopes located at an altitude of 2200 m a.s.l. in the Canary...
Limits on the Hard X-Ray Emission From the Periodic Fast Radio Burst FRB 180916.J0158+65
FRB 180916.J0158+65 is one of the nearest, periodically repeating, and actively bursting fast radio bursts (FRBs) that has been localized to the outskirts of a...
