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.
NRAO and GBO Saddened at Loss of Arecibo Telescope
The National Radio Astronomy Observatory (NRAO) and the Green Bank Observatory (GBO) are saddened by the announcement of the decommissioning of the Arecibo Telescope in Puerto Rico due to recent and devastating structural damage. See the National Science Foundation’s full release here.
The 305-meter Arecibo radio telescope has a long and distinguished history of landmark contributions to astronomy and planetary science and often has been a valued partner with NRAO telescopes and the Green Bank Telescope in research projects. Its loss will be a blow to science.
The staff and facilities of NRAO and GBO stand ready to assist in filling the gap that this loss will create, and offer our best wishes to our colleagues who are affected by this development.
Frequently Asked Questions:
Can any NRAO facilities or the Green Bank Telescope replace the Arecibo Telescope?
While some instruments of the NRAO and GBO can perform some of the Arecibo Telescope’s functions, none will be a total replacement for its capabilities. The Arecibo Telescope is irreplaceable.
Does the NRAO or GBO support the NSF’s move to decommission the telescope?
We defer to the engineers’ reports evaluating the devastating damage done to the telescope’s infrastructure and threats to staff safety, as shared in the NSF’s release.
Will the NRAO or GBO be providing support to the staff displaced by this event?
We encourage AO staff displaced by this loss to consider any of our current open opportunities with the NRAO or GBO.
