Abstract:Galaxies in the Universe are distributed in a web-like structure characterized by different large-scale environments: dense clusters， elongated filaments， sheetlike walls and under-dense regions， called voids. The low density in voids is expected to affect the properties of their galaxies. Indeed， previous studies have shown that galaxies in voids are， on average， bluer and less massive， and have later morphologies and higher current star formation rates than galaxies in denser large-scale environments. However， it has never been observationally proved that the star formation histories in voids are substantially different from those in filaments， walls and clusters. Here we show that void galaxies have had， on average， slower SFHs than galaxies in denser large-scale environments. We also find two main SFH types present in all the environments: ‘short-timescale’ galaxies are not affected by their large-scale environment at early times but only later in their lives;
Galaxy clusters magnify background objects through strong gravitational lensing. Typical magnifications for lensed galaxies are factors of a few but can also be as high as tens or hundreds， stretching galaxies into giant arcs. Individual stars can attain even higher magnifications given fortuitous alignment with the lensing cluster. Recently， several individual stars at redshifts between approximately 1 and 1.5 have been discovered， magnified by factors of thousands， temporarily boosted by microlensing. Here we report observations of a more distant and persistent magnified star at a redshift of 6.2 ± 0.1， 900 million years after the Big Bang. This star is magnified by a factor of thousands by the foreground galaxy cluster lens WHL0137–08 ， as estimated by four independent lens models. Unlike previous lensed stars， the magnification and observed brightness have remained roughly constant over 3.5 years of imaging and follow-up. The delensed absolute UV magnitude， −10 ± 2， is consistent with a star of mass greater than 50 times the mass of the Sun. Confirmation and spectral classification are forthcoming from approved observations with the James Webb Space Telescope.
Abstract:Here we report the highest magmatic 3He/4He ratio yet measured in terrestrial igneous rocks， in olivines from Baffin Island lavas. We argue that the extremely high-3He/4He helium in these lavas might derive from Earth’s core. The viability of the core hypothesis relaxes the long-standing constraint—based on noble gases in lavas associated with mantle plumes globally—that volatile elements from the solar nebula have survived in the mantle since the early stages of accretion.
我们的研究结果阐明了鸣禽如何进化出简单的曲调，并指出了性选择影响“声乐学习”的不同策略。Abstract:Here， by applying dimensionality-reduction techniques to the singing behaviour of zebra finches ， we show that syllable spread in low-dimensional feature space explains how single songs function as honest indicators of fitness. We find that this Gestalt measure of behaviour captures the spectrotemporal distinctiveness of song syllables in zebra finches;
Abstract:Decay of a particle into more particles is a ubiquitous phenomenon to interacting quantum systems， taking place in colliders， nuclear reactors or solids. In a nonlinear medium， even a single photon would decay by down-converting into lower-frequency photons with the same total energy， at a rate given by Fermi’s golden rule. However， the energy-conservation condition cannot be matched precisely if the medium is finite and only supports quantized modes. Here we implement such an experiment using a superconducting multimode cavity， the nonlinearity of which was tailored to strongly violate the photon-number conservation. The resulting interaction attempts to convert a single photon excitation into a shower of low-energy photons but fails owing to the many-body localization mechanism， which manifests as a striking spectral fine structure of multiparticle resonances at the standing-wave-mode frequencies of the cavity. Each resonance was identified as a many-body state of radiation composed of photons from a broad frequency range and not obeying Fermi’s golden rule theory. Our result introduces a new platform to explore the fundamentals of many-body localization without having to control many atoms or qubits.
