The First Accurate Parallax Distance to a Black Hole by Miller-Jones, James, Jonker, P., Dhawan, V., Brisken, W., Rupen, M., Nelemans, G., Gallo, E.

“…Using astrometric VLBI observations, we have determined the parallax of the black hole X-ray binary V404 Cyg to be 0.418 ± 0.024 mas, corresponding to a distance of 2.39 ± 0.14 kpc, significantly lower than the previously accepted value. …”

The first low-mass black hole x-ray binary identified in quiescence outside of a globular cluster by Tetarenko, B., Bahramian, A., Arnason, R., Miller-Jones, James, Repetto, S., Heinke, C., MacCarone, T., Chomiuk, L., Sivakoff, G., Strader, J., Kirsten, Franz, Vlemmings, W.

“…They showed that the parallax of this flat-spectrum variable radio source indicates a - + 2.2 0.30.5 kpc distance, which identifies it as lying in the foreground of the GC M15. …”

The geometric distance and binary orbit of PSR B1259-63 by Miller-Jones, James, Deller, A., Shannon, Ryan, Dodson, R., Moldón, J., Ribó, M., Dubus, G., Johnston, S., Paredes, J., Ransom, S., Tomsick, J.

“…Using the Australian Long Baseline Array, we have conducted very long baseline interferometric observations of PSR B1259-63 over 4.4 years, fully sampling the 3.4-year orbital period. From our measured parallax of 0.38 ± 0.05 maswe use a Bayesian approach to infer a distance of 2.6+0.4-0.3 kpc. …”

MOA-2011-BLG-262Lb: A sub-earth-mass moon orbiting a gas giant primary or a high velocity planetary system in the galactic bulge by Bennett, D., Batista, V., Bond, I., Bennett, C., Suzuki, D., Beaulieu, J., Udalski, A., Donatowicz, J., Bozza, V., Abe, F., Botzler, C., Freeman, M., Fukunaga, D., Fukui, A., Itow, Y., Koshimoto, N., Ling, C., Masuda, K., Matsubara, Y., Muraki, Y., Namba, S., Ohnishi, K., Rattenbury, N., Saito, T., Sullivan, D., Sumi, T., Sweatman, W., Tristram, P., Tsurumi, N., Wada, K., Yock, P., Albrow, M., Bachelet, E., Brillant, S., Caldwell, J., Cassan, A., Cole, A., Corrales, E., Coutures, C., Dieters, S., Dominis Prester, D., Fouqué, P., Greenhill, J., Horne, K., Koo, J., Kubas, D., Marquette, J., Martin, R., Menzies, J., Sahu, K., Wambsganss, J., Williams, Andrew, Zub, M., Choi, J., Depoy, D., Dong, S., Gaudi, B., Gould, A., Han, C., Henderson, C., McGregor, D., Lee, C., Pogge, R., Shin, I., Yee, J., Szymanski, M., Skowron, J., Poleski, R., Kozlowski, S., Wyrzykowski, Kubiak, M., Pietrukowicz, P., Pietrzynski, G., Soszynski, I., Ulaczyk, K., Tsapras, Y., Street, R., Dominik, M., Bramich, D., Browne, P., Hundertmark, M., Kains, N., Snodgrass, C., Steele, I., Dekany, I., Gonzalez, O., Heyrovský, D., Kandori, R., Kerins, E., Lucas, P.

“…The data constrain the product ML p rel where ML is the lens system mass and prel is the lens-source relative parallax. If the lens system is nearby (large prel), then ML is small (a few Jupiter masses) and the companion is a sub-Earth-mass exomoon. …”

A Multiwavelength View of the Neutron Star Binary 1FGL J1417.7-4402: A Progenitor to Canonical Millisecond Pulsars by Swihart, S., Strader, J., Shishkovsky, L., Chomiuk, L., Bahramian, A., Heinke, C., Miller-Jones, James, Edwards, P., Cheung, C.

“…We show that one of the main pieces of evidence previously put forward for an accretion disk—the complex morphology of the persistent Hα emission line—can be better explained by the presence of a strong, magnetically driven stellar wind from the secondary and its interaction with the pulsar wind. …”

The Galactic Center Lobe as an H ii Region by Anderson, Loren, Luisi, M., Liu, B., Linville, D.J., Benjamin, R.A., Hurley-Walker, Natasha, McClure-Griffiths, N.M., Zucker, C.

“…We search for the ionizing source(s) of the possible H ii region and identify a stellar cluster candidate (Camargo #1092/Ryu & Lee #532) and a cluster of young stellar objects (the SPICY cluster G359.3+0.3) whose members have Gaia parallaxes distances of 1.7 ± 0.4 kpc. …”
