High-redshift GRBs can probe the star formation and reionization history of the early Universe, but their detection remains rare. Here we report the detection of a GRB triggered in the 0.5–4 keV band by the Wide-field X-ray Telescope (WXT) on board the Einstein Probe (EP) mission, designated as EP240315a, whose bright peak was also detected by the Swift Burst Alert Telescope and Konus-Wind through off-line analyses. At a redshift of <i>z</i> = 4.859, EP240315a showed a much longer and more complicated light curve in the soft-X-ray band than in gamma rays. Benefiting from a large field of view (~3,600°²) and a high sensitivity, EP-WXT captured the earlier engine activation and extended late engine activity through a continuous detection. With a peak X-ray flux at the faint end of previously known high-<i>z</i> GRBs, the detection of EP240315a demonstrates the great potential for EP to study the early universe via GRBs.</p>","PeriodicalId":18778,"journal":{"name":"Nature Astronomy","volume":"75 1","pages":""},"PeriodicalIF":14.1,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this initial phase of particle growth faces constraints, notably from destructive encounters. To find the maximum particle size achievable, we studied collisional processes during a prolonged microgravity experiment aboard a suborbital flight. Specifically, we describe an impact erosion limit. We observed individual basalt beads, each measuring 0.5 mm in diameter, colliding with and either eroding or adhering to a cluster several centimetres in size. This cluster, formed from tribocharged particles, simulates an electrostatic growth phase that surpasses the classical bouncing barrier. We found a threshold velocity of about 0.5 m s⁻¹, which separates additive and erosive impacts of individual beads. Numerical simulations of grains impacting clusters, for both low and high charge constituents, corroborate the experimental findings of surface erosion within the observed velocity range. This specific velocity threshold supports the potential formation of pebbles several centimetres in size within protoplanetary disks. Such dimensions place these pebbles well into a regime in which hydrodynamic interactions might facilitate the formation of planetesimals.</p>","PeriodicalId":18778,"journal":{"name":"Nature Astronomy","volume":"62 1","pages":""},"PeriodicalIF":14.1,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142991875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various theoretical attempts have been made to explain the elusive nature of dark energy. One of the compelling theories is the so-called symmetron dark energy, which predicts a fifth force that interacts with matter. However, the screening of the fifth force in high-density environments poses a challenge for laboratory experiments. Although several experiments have constrained certain aspects of the model’s parameter space, there is still a vast and unexplored region. Here we have constructed an experimental platform based on a magnetically levitated force sensor with a specially designed structure to search for the symmetron fifth force at the submillimetre scale and minimize screening effects. We have improved the limits of the model by over six orders of magnitude within the three-dimensional parameter space.
