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.

Next Generation Very Large Array Workshop 2016

AAS Meeting Venue: Gaylord Palms Convention Center, Sun B
Kissimmee, Florida, USA
Radio astronomy is playing a leading role in opening new discovery space, imaging the earliest phases of planet and star formation, studying the cool dust and gas that drive star formation in galaxies across cosmic time, observing energetic and time-varying phenomena ranging from compact stars to distant Active Galactic Nuclei, and testing the fundamental laws of physics and cosmology.
Inspired by dramatic discoveries from the Jansky Very Large Array and the Atacama Large Millimeter/submillimeter Array (ALMA), the community has initiated discussion of a future facility at short centimeter wavelengths that will enable a major step in imaging thermal emission from the cosmos at milliarcsecond resolution: a next generation Very Large Array (ngVLA). The past year has seen rapid progress in the ngVLA science case and technical requirements, building from an NRAO-sponsored community workshop held at the January 2015 American Astronomical Society (AAS) meeting. The ngVLA is part of the broader astronomy community discussion of future science opportunities and instrumentation.
The NRAO is organizing a one-day workshop on Monday, 4 January 2016 to discuss concepts for a next generation Very Large Array (ngVLA). This workshop will take place immediately prior to the January 2016 American Astronomical Society (AAS) meeting in Kissimmee, Florida, and will update the AAS membership on progress toward the ngVLA concept.
This ngVLA Workshop will foster broad community discussion of the ngVLA science case and technical challenges and will include:
- Presentation of the current ngVLA science program by community leaders;
- Discussion of the technical requirements and challenges emerging from the science program;
- Contributed science talks that expand the ngVLA science case; and
- Discussion of ngVLA synergies with other science facilities, such as ALMA, James Webb Space Telescope, High Definition Space Telescope, Square Kilometre Array, and Thirty Meter Telescope.
This ngVLA Workshop will span a full day (9 a.m. – 5 p.m. EST). The morning will be dedicated to science presentations, and the afternoon will focus on high-level technical issues, with substantial open discussion time. We request attendees register so that we can be adequately plan for seating and refreshments, but registration is not required to attend.
Visit the ngVLA Project webpages for additional information. There is no fee for registration or attendance, but please register so we have an accurate head count for the workshop.
No fee, but please register for head count.
We look forward to seeing everyone in Kissimmee on Monday, 4 January 2016!
