Gaia parallax bias via spherical harmonics: A Python tool and discussion of possible causes
Valeri V. Makarov, Ciprian T. Berghea
Parallaxes in Gaia DR3 are known to suffer from a complex set of sky-correlated and magnitude-dependent offsets or biases at the level of a few tens of as. Estimated from a samp…
High-resolution Pan-STARRS and SMA observations of IRAS 23077+6707: A giant edge-on protoplanetary disk
Kristina Monsch, Joshua B. Lovell, Ciprian T. Berghea +6
We present resolved images of IRAS 23077+6707 ("Dracula's Chivito") in 1.3 mm/225 GHz thermal dust and CO gas emission with the Submillimeter Array (SMA) and optical (0.5-$0.8\,μ\m…
Dracula's Chivito: discovery of a large edge-on protoplanetary disk with Pan-STARRS
Ciprian T. Berghea, Ammar Bayyari, Michael L. Sitko +6
We report the serendipitous discovery of a large edge-on protoplanetary disk associated with the infrared source IRAS 23077+6707. The disk's apparent size in the Pan-STARRS (PS1) i…
A Highly Magnified Gravitationally Lensed Red QSO at z = 2.5 with a Significant Flux Ratio Anomaly
Eilat Glikman, Cristian E. Rusu, Geoff C. -F. Chen +12
We present the discovery of a gravitationally lensed dust-reddened QSO at z = 2.517, identified in a survey for QSOs by infrared selection. Hubble Space Telescope imaging reveals a…
Optical variability of ICRF3 quasars in the Pan-STARRS 3Pi survey with functional principal components analysis
C. T. Berghea, V. V. Makarov, K. Quigley +1
We make use of individual (epoch) detection data from the Pan-STARRS 3Pi survey for 2863 optical ICRF3 counterparts in the five wavelength bands g, r, i, z, and y, published as par…
Detection of a Radio Bubble around the Ultraluminous X-ray Source Holmberg IX X-1
Ciprian T. Berghea, Megan C. Johnson, Nathan J. Secrest +3
We present C and X-band radio observations of the famous utraluminous X-ray source (ULX) Holmberg IX X-1, previously discovered to be associated with an optical emission line nebul…
