We analyse eight epochs of Hubble Space Telescope Hα+[N ii] imaging of η Carinae's outer
ejecta. Proper motions of nearly 800 knots reveal that the detected ejecta are divided into …

… Despite this complication, the proper motions we measure in HH 901 agree with those
obtained by Reiter & Smith (2014) within the uncertainties (see Fig. 4 and Table 3). …

HH 666 is an externally irradiated protostellar outflow in the Carina nebula for which we
present new near-IR [Fe ii] spectra obtained with the Folded-Port Infrared Echellette …

We constrain the proper motions of five OB stars associated with candidate stellar wind bow
shocks in the Carina Nebula using Hubble Space Telescope ACS imaging over 9–10 yr …

We report the discovery in Hubble Space Telescope (HST) images of the new Herbig–Haro
jet, HH 1019, located near the Tr 14 cluster in the Carina Nebula. Like other HH jets in the …

η Carinae, the most extreme luminous blue variable in our Galaxy, underwent a Great Eruption
in the 1800s and ejected significant mass into the well-known bipolar Homunculus. But η …

… Many thanks are owed to my collaborators and most especially to Megan Reiter, who—among
many other things—reminded me that talking science can be fun. I will be forever grateful …

… ii] lines can also penetrate the extinction inside the dusty birthplaces of these jets, allowing
us to connect the larger Hα outflows to the Spitzer-identified protostars that drive them (Reiter …

We conducted a radial velocity survey of the Cyg OB2 association over a 6 yr (1999-2005)
time interval to search for massive close binaries. During this time we obtained 1139 spectra …

We have obtained multi-epoch observations of 31 O-type stars in the Carina Nebula using
the CHIRON spectrograph on the CTIO/SMARTS 1.5-m telescope. We measure their radial …
