Unlocking AGN Variability with Custom ZTF Photometry for High-Fidelity Light Curves and Robust Selection
P. Arévalo, P. Sánchez-Sáez, B. Sotomayor +3
(Abridged)We explore the potential of optical variability selection methods to identify AGN, including those challenging to detect with conventional techniques. Using the unprecede…
Orientation effects on cool gas absorption from gravitational-arc tomography of a z = 0.77 disc galaxy
A. Fernandez-Figueroa, S. Lopez, N. Tejos +11
We use spatially-resolved spectroscopy of a distant giant gravitational arc to test orientation effects on MgII absorption equivalent width (EW) and covering fraction (kappa) in th…
A multiple planet system of super-Earths orbiting the brightest red dwarf star GJ887
S. V. Jeffers, S. Dreizler, J. R. Barnes +29
The nearest exoplanets to the Sun are our best possibilities for detailed characterization. We report the discovery of a compact multi-planet system of super-Earths orbiting the ne…
Observations in the 1.3 and 1.5 THz Atmospheric Windows with the Receiver Lab Telescope
D. P. Marrone, R. Blundell, E. Tong +5
The Receiver Lab Telescope (RLT) is a ground-based terahertz telescope; it is currently the only instrument producing astronomical data between 1 and 2 THz. The capabilities of the…
An optical bow shock around the nearby millisecond pulsar J2124-3358
Bryan Gaensler, Heath Jones, Ben Stappers
We report the discovery of an H-alpha-emitting bow-shock nebula powered by the nearby millisecond pulsar J2124-3358. The bow shock is very broad, and is highly asymmetric about the…
The nature of ultraluminous X-ray sources in nearby galaxies
T. P. Roberts, M. R. Goad, M. J. Ward +2
The advanced capabilities of the Chandra and XMM-Newton observatories mean that, for the first time, the detailed study of the brightest point-like X-ray sources in nearby galaxies…
