    PROPERTIES OF THE 24 DAY MODULATION IN GX 13+1 FROM NEAR-INFRARED AND X-RAY OBSERVATIONS by Corbet, Robin H. D., Pearlman, Aaron B., Buxton, Michelle, Levine, Alan M.

    Published 2015
    “…We present here the results of (1) K-band photometry obtained with the SMARTS Consortium CTIO 1.3 m telescope on 68 nights over a 10 month interval; (2) continued monitoring with the RXTE ASM, analyzed using a semi-weighted power spectrum instead of the data filtering technique previously used; and (3) Swift Burst Alert Telescope (BAT) hard X-ray observations. …”

    AROUND 200 NEW X-RAY BINARY IDs FROM 13 YR OF CHANDRA OBSERVATIONS OF THE M31 CENTER by Barnard, R., Garcia, M. R., Primini, F., Li, Z., Murray, Stephen S., Baganoff, Frederick K

    Published 2015
    “…We have 174 Chandra observations spaced at ~1 month intervals due to our transient monitoring program, deeper observations of the M31 nucleus, and some public data from other surveys. …”

    EFFECTS OF FAST AND SLOW SOLAR WIND ON THE ENERGETIC NEUTRAL ATOM (ENA) SPECTRA MEASURED BY THE INTERSTELLAR BOUNDARY EXPLORER (IBEX) AT THE HELIOSPHERIC POLES by Dayeh, M. A., McComas, David J., Allegrini, F., DeMajistre, R., Desai, M. I., Funsten, H. O., Janzen, Paul H., Livadiotis, G., Randol, B. M., Reisenfeld, D. B., Schwadron, N. A., Vanderspek, Roland K

    Published 2015
    “…We study the energy dependence of ~0.5-6 keV energetic neutral atom (ENA) spectra in the southern heliospheric polar region obtained during five six-month sky maps measured by IBEX-Hi. We calculate the spectral slopes in the south pole in four different energy bands, namely, ~0.7-1.1 keV, ~1.1-1.7 keV, ~1.7-2.7 keV, and ~2.7-4.3 keV. …”

    ROSSI X-RAY TIMING EXPLORER AND BeppoSAX OBSERVATIONS OF THE TRANSIENT X-RAY PULSAR XTE J1859+083 by Corbet, Robin H. D., in't Zand, J. J. M., Marshall, F. E., Levine, Alan M

    Published 2015
    “…Eighteen sets of PCA observations were obtained over an approximately one month interval in 1999. The flux variability measured with the PCA appears consistent with the possible period found with the ASM. …”

    THE 2003 OUTBURST OF THE X-RAY TRANSIENT H1743–322: COMPARISONS WITH THE BLACK HOLE MICROQUASAR XTE J1550–564 by McClintock, Jeffrey E., Rupen, Michael P., Torres, M. A. P., Steeghs, D., Levine, Alan M., Orosz, Jerome A., Remillard, Ronald A

    Published 2015
    “…The bright X-ray transient H1743−322 was observed daily by the Rossi X-ray Timing Explorer during most of its eight-month outburst in 2003. We present a detailed spectral analysis and a supporting timing analysis of all of these data, and we discuss the behavior and evolution of the source in terms of the three principal X-ray states defined by Remillard and McClintock. …”

    AN X-RAY VIEW OF THE JET CYCLE IN THE RADIO-LOUD AGN 3C120 by Lohfink, Anne M., Reynolds, Christopher S., Jorstad, Svetlana G., Marscher, Alan P., Miller, Eric D., Aller, Hugh, Aller, Margo F., Brenneman, Laura W., Fabian, Andrew C., Miller, Jon M., Mushotzky, Richard F., Nowak, Michael A., Tombesi, Francesco

    Published 2015
    “…The idea of a refilling disk is further supported by the detection of the ejection of a new jet knot approximately one month after the Suzaku pointings. We also discover a step-like event in one of the Suzaku pointings in which the soft band lags the hard band. …”

    A STRONGLY HEATED NEUTRON STAR IN THE TRANSIENT Z SOURCE MAXI J0556-332 by Homan, Jeroen, Fridriksson, Joel K., Wijnands, Rudy, Cackett, E. M., Degenaar, N., Linares, Manuel Alegret, Lin, Dacheng, Remillard, Ronald A

    Published 2015
    “…Observations of the source made during outburst (with the Rossi X-ray Timing Explorer) reveal tracks in its X-ray color-color and hardness-intensity diagrams that closely resemble those of the neutron-star Z sources, suggesting that MAXI J0556-332 had near- or super-Eddington luminosities for a large part of its ~16 month outburst. A comparison of these diagrams with those of other Z sources suggests a source distance of 46 ± 15 kpc. …”
