High-energy transient signals are most often determined to be gamma-ray burst events, but the recently-launched Einstein Probe has expanded astronomers’ ability to quickly respond to similar signals occurring at X-ray wavelengths. Now, a multi-wavelength study of EP240408a concludes that while many of the signal’s characteristics might lead to the conclusion that it is a gamma-ray burst, the non-detection at radio wavelengths precludes that possibility.

Students Contribute to New Understanding of ‘Twinkling’ Pulsars
The flexible observing setup of the Green Bank Observatory’s 20-meter telescope enabled frequent, long-duration observations of eight pulsars, spanning two and a half years for a student-driven study carried out by students in the Pulsar Science Collaboratory program.
Double the Disks, Double the Discovery: New Insights into Planet Formation in DF Tau
Tucked away in a star-forming region in the Taurus constellation, a pair of circling stars are displaying some unexpected differences in the circumstellar disks of dust and gas that surround them. A new study led by researchers at Lowell Observatory, combining data from the Atacama Large Millimeter/submillimeter Array (ALMA) and Keck Observatory, has unveiled intriguing findings about planet formation in this binary star system, known as DF Tau, along with other systems in this region.
Situation In Northern Chile / Situacion En El Norte De Chile
AUI would like to express its deep concern and sympathy for the families affected by the storms and landslides in northern Chile over the past days. Our thoughts go to the people who have lost loved ones or suffered material losses.
The ALMA Observatory received substantial snowfall, but all its staff is well and its infrastructure and equipment are unharmed. Normal operations should resume shortly.
Many ALMA employees reside or have relatives in the II, III and IV regions. We understand that their families are safe. Some staff members have experienced delays travelling back home at the end of their shifts; we hope that they are able to join their families soon.
SITUACION EN EL NORTE DE CHILE
AUI quiere manifestar su consternación y gran preocupación por las familias afectadas a raíz de los temporales y aluviones que han ocurrido en el norte del país en días recientes. Acompañamos a aquellas personas que han perdido seres queridos o sufrido pérdidas materiales.
Hubo intensas nevadas en el Observatorio ALMA, pero afortunadamente todos sus trabajadores se encuentran bien, y su infraestructura y equipos no han sufrido daños. Se espera una normalización de las operaciones a la brevedad.
Muchos trabajadores de ALMA viven o tienen parientes en las regiones II, III o IV; entendemos que sus familiares se encuentran a salvo. Sin embargo, algunos trabajadores han tenido retrasos para volver a sus hogares. Esperamos que se puedan reunir con sus familias prontamente.
