We used direct observations, camera traps, and environmental DNA (eDNA) to identify secondary consumers of sap from wells created by red‐naped (S. nuchalis) and Williamson's (S. thyroideus) sapsuckers among three groups of shrubs and trees in south‐central Colorado, USA.

The Era of Kilometer‐Scale Neutrino Detectors
Neutrino astronomy beyond the Sun was first imagined in the late 1950s; by the 1970s, it was realized that kilometer‐scale neutrino detectors were required. The first such instrument, IceCube, transforms a cubic kilometer of deep and ultra‐transparent Antarctic ice into a particle detector.

Isotope analysis of predator feces and consumed prey remains can be used to non‐invasively track diet and reconstruct past environment and climate conditions. However, one must account for the isotopic difference between diet and feces, as well as the possible influence of digestion on consumed prey tissues.

Core‐collapse supernovae are dramatic explosions marking the catastrophic end of massive stars. The only means to get direct information about the supernova engine is from observations of neutrinos emitted by the forming neutron star, and through gravitational waves which are produced when the hydrodynamic flow or the neutrino flux is not perfectly ...

ABSTRACT Aim The aim of the current study is to conduct a comprehensive phylogenetic analysis of the genus Arbacia to elucidate the evolution and phylogenetic relationships among all extant species and reevaluate the presence of geographic structure within species that have wide, fragmented distributions.

Pulsar‐Driven Jets in Supernovae, Gamma‐Ray Bursts, and the Universe
The bipolarity of Supernova 1987A can be understood through its very early light curve from the CTIO 0.4 m telescope and IUE FES and following speckle observations of the “Mystery Spot”. These indicate a beam/jet of light/particles, with initial collimation factors >104 and velocities >0.95 c, involving up to 10−5 M⊙ interacting with circumstellar ...

Highly-Ionized High-Velocity Gas in the Vicinity of the Galaxy [PDF]
We report the results of an extensive FUSE study of high velocity OVI absorption along 102 complete sight lines through the Galactic halo. The high velocity OVI traces a variety of phenomena, including tidal interactions with the Magellanic Clouds ...

THE TIDAL ORIGIN OF THE MAGELLANIC STREAM AND THE POSSIBILITY OF A STELLAR COUNTERPART [PDF]
We present an N-body model that reproduces the morphology and kinematics of the Magellanic Stream (MS), a vast neutral hydrogen (H i) structure that trails behind the Large and Small Magellanic Clouds (LMC and SMC, respectively) in their orbit about the ...

Spectral Studies of Super‐Eddington Accreting Neutron Stars in the Magellanic Clouds
ABSTRACT Major outbursts of BeXRBs offer a unique laboratory for studying accretion onto magnetized neutron stars (NSs) over a large dynamic range. The accreting material is entrained from the accretion disk by the strong magnetic field, and then channeled onto the NS, forming a so‐called accretion column (AC).
