Keith Smith Keith Smith Gas within the Solar System's heliosphere emits a complex pattern of soft X-rays. Dennerl et al. use the eROSITA X-ray survey to disentangle this foreground emission and determine where in the heliosphere it comes from. ☄️☀️🔭 #heliophysics #highenergyastro www.science.org/doi/10.1126/...
ESO Astronomers spot mysterious gamma-ray explosion, unlike any detected before! 💥 Our VLT revealed that its source lies outside our galaxy. Yet its cause is still unknown 🤔 Read more: https://www.eso.org/public/news/eso2514/ 🔭 🧪 ☄️ #extragalactic #highenergyastro
Jamie Zvirzdin I remotely operate sensitive cosmic-ray telescopes in the West Desert of Utah. Wild that we can pick up the light from this wildfire. Be safe, Sevier County! Select Band="Fire Temperature RGB" www.star.nesdis.noaa.gov/goes/wfo_ban... #Utah #UofU #TelescopeArray #highenergyastro 🧪
Huei Sears, PhD 🌟 @genevieveschroeder.bsky.social (Cornell) et al. present late-time radio imaging of a sample of SNe Ic-BL. In the images here, at the optical location (left) of SN PTF10tqv, they detect very late-time (> 10 years !!!) emission with the VLA (middle) and MeerKAT (right). 🧪🔭☄️👩🔬 #highenergyastro

Fun visit to the @einsteintelescope.bsky.social pathfinder at @maastrichtu.bsky.social yesterday with my research group. Really cool developments in the making, thanks very much for the great tour! #highenergyastro

Huei Sears, PhD 🌟 Mingyu Li, a third-year graduate student at Tsinghua University in Beijing, leads new JWST, ALMA, + VLA work on a pair of active ring galaxies. Appearing as a "Cosmic Owl," their overlap creates a bright, blue star-forming region - the "beak" in the figure. #highenergyastro 🔭🧪☄️🦉 arXiv: 2506.10058

Jamie Zvirzdin A room with a GREAT view. Currently waiting for lightning to clear up before we can open #UofU #TelescopeArray doors and capture ultrahigh-energy cosmic-ray particles. Also studying for #JHU graduate course, Chaos and Its Applications. Also, cat. #highenergyastro #fundscience 🧪⚛️ #particlephysics

Huei Sears, PhD 🌟 Excited to announce the 'Rutgers Summer Transient Soiree' this July 16-18! To offset the uncertain funding landscape, we are offering a hybrid option + requiring NO registration fee. Non-faculty are especially encouraged to apply! Please apply by May 31! More in the replies! 🧪🔭☄️ #highenergyastro
Huei Sears, PhD 🌟 v excited to see this work from @astrobonk.bsky.social on the arXiv !! In this, Rebecca Kyer + report the discovery of two Galactic accreting compact objects consistent with being transitional millisecond pulsars !! I worked on this optical variability plot with Rebecca !! 🧪🔭☄️ #highenergyastro
Huei Sears, PhD 🌟 Michaela Schwab's first first-author paper is now out! She analyzes HST imaging at ~2500 (!!!) days post-maximum and finds there is still (still) a flux excess! She is PI of a HST program that will be revisiting this source to keep tracking the evolution! 🔭🧪☄️👩🔬 #highenergyastro #womeninstem
Huei Sears, PhD 🌟 ah !! new from Fabio Ragosta (Università di Napoli Federico II) et al. who find support that SN 2015ap originated from a binary star system ! Figure 1 (below) shows the publicly-available light curve of SN 2015ap, and I really like that the points are little stars ! 🧪🔭☄️ #highenergyastro
Huei Sears, PhD 🌟 It's been a long time coming... the paper I led on GRB 221009A was recently accepted for publication by ApJ ! : ) Check out this poster I made for the project for the upcoming 'Celebrating 20 Years of Swift Discoveries' Conference !! 🧪🔭☄️ #highenergyastro #womeninSTEM
Jamie Zvirzdin So satisfying to create plots like this. #Relativity #gradschool #Python #JupyterNotebooks #differentialgeometry #highenergyastro ⚛️
Jamie Zvirzdin I flew over Greenland on my way to a physics ⚛️ conference. Some of my colleagues have #highenergyastro experiments going in peace and quiet, interrupted only by intermittent polar bears. Let's keep it this way. 🧪
