Optical Flashes from Beam-Driven Light Sails with the Roman, Rubin and Euclid Observatories
James Guillochon, Abraham Loeb
The primary challenge of rocket propulsion is the burden of accelerating the spacecraft's own fuel. Light sails leave the propellant at home, with the achievable speed set by the s…
Three-Dimensional Expansion of Iron Ejecta in Cassiopeia A with Chandra and XRISM
Aya Bamba, Tomoki Kadoya, Kouichi Hagino +4
Measurement of the expansion structure of ejecta in supernova remnants (SNRs) provides important information about their explosion mechanism. We combine Chandra proper-motion measu…
X-ray Halos of Early-Type Galaxies with AGN Feedback and Accretion from a Circumgalactic Medium: models and observations
Silvia Pellegrini, Luca Ciotti, Zhaoming Gan +2
The knowledge of the X-ray properties of the hot gas halos of early-type galaxies has significantly advanced in the past years, for large and homogeneously investigated samples. We…
The New Science of Unidentified Aerospace-Undersea Phenomena (UAP)
Kevin H. Knuth, Philippe Ailleris, Hussein Ali Agrama +36
After decades of dismissal and secrecy, it has become clear that a significant number of the world's governments take Unidentified Aerospace-Undersea Phenomena (UAP), formerly know…
Absorption and Self-Absorption of [C II] and [O I] Far Infrared Lines Towards a Bright Bubble in the Nessie Infrared Dark Cloud
J. M. Jackson, J. S. Whitaker, E. T. Chambers +15
Using the upGREAT instrument on SOFIA, we have imaged [C II] 157.74 and [O I] 63.18 micron line emission from a bright photodissociation region (PDR) associated with an ionized ``b…
The 2021 outburst of the recurrent nova RS Ophiuchi observed in X-rays by the Neil Gehrels Swift Observatory: a comparative study
K. L. Page, A. P. Beardmore, J. P. Osborne +12
On 2021 August 8, the recurrent nova RS Ophiuchi erupted again, after an interval of 15.5 yr. Regular monitoring by the Neil Gehrels Swift Observatory began promptly, on August 9.9…
