A Vigorous Explorer Program (2009)
Elvis, Martin, Beasley, Matthew, Brissenden, Roger, Chakrabarti, Supriya, Cherry, Michael, Devlin, Mark, ...
Explorers have made breakthroughs in many fields of astrophysics. The science from both these missions contributed to three Nobel Prizes - Giacconi (2002), Mather, and Smoot (2006). Explorers have:...
The young stellar population of NGC 4214 as observed with HST. I. Data and methods (2007)
Úbeda, Leonardo, Maíz-Apellániz, J., MacKenty, John
We present the data and methods that we have used to perform a detailed UV-optical study of the nearby dwarf starburst galaxy NGC 4214 using multifilter HST/WFPC2+STIS photometry. We explain the...
The young stellar population of NGC 4214 as observed with HST. II. Results (2007)
Úbeda, Leonardo, Maíz-Apellániz, J., MacKenty, John
We present the results of a detailed UV-optical study of the nearby dwarf starburst galaxy NGC 4214 using multifilter HST/WFPC2+STIS photometry. The stellar extinction is found to be quite patchy,...
A massive cluster of Red Supergiants at the base of the Scutum-Crux arm (2007)
Davies, Ben, Figer, Don F., Kudritzki, Rolf-Peter, MacKenty, John, Najarro, Francisco, Herrero, Artemio
We report on the unprecedented Red Supergiant (RSG) population of a massive young cluster, located at the base of the Scutum-Crux Galactic arm. We identify candidate cluster RSGs based on {\it 2MASS}...

Discovery of an Extraordinarily Massive Cluster of Red Supergiants (2006)
Figer, Donald F., MacKenty, John, Robberto, Massimo, Smith, Kester, Najarro, Francisco, Kudritzki, Rolf P., ...
We report the discovery of an extraordinarily massive young cluster of stars in the Galaxy, having an inferred total initial cluster mass comparable to the most massive young clusters in the Galaxy....
Crotts, Arlin, Garnavich, Peter, Priedhorsky, William, Habib, Salman, Heitmann, Katrin, Wang, Yun, ...
JEDI will probe dark energy in three independent ways by measuring the expansion history of the universe: (1) using type Ia supernovae as cosmological standard candles over a range of distances, (2)...

Far-Ultraviolet Imaging of the Field Star Population in the Large Magellanic Cloud with HST (1998)
Brosch, Noah, Shara, Michael, MacKenty, John, Zurek, David, McLean, Brian
We present an analysis of the deepest pure-UV observations with the highest angular resolution ever performed, a set of 12 exposures with the HST WFPC2 and F160BW filter obtained in parallel...
Schmidt, Maarten, Hasinger, Guenther, Gunn, James, Schneider, Don, Burg, Richard, Giacconi, Riccardo, ...
The ROSAT Deep Survey includes a complete sample of 50 X-ray sources with fluxes in the $0.5 - 2$ keV band larger than 5.5 $10^{-15}$ erg cm$^{-2}$ s$^{-1}$ in the Lockman field (Hasinger et al.,...
