      Calderón, D.; Cuadra, J.; Schartmann, M.; Burkert, A.; Prieto, J.; Russell, C. M. P. (Oxford University Press, 2020)
      The inner parsec of our Galaxy contains tens of Wolf-Rayet stars whose powerful outflows are constantly interacting while filling the region with hot, diffuse plasma. Theoretical models have shown that, in some cases, the ...

      The tidal disruption of a star by a nuclear supermassive black hole was predicted in the 1970s and first confirmed by soft X-ray flares seen from quiescent galaxies in the ROSAT all-sky survey. We report here on the discovery ...
    • Tidal modulation of continuous nonvolcanic seismic tremor in the Chile triple junction region 
      Gallego, A.; Russo, R. M.; Comte Selman, Diana; Mocanu, V.; Murdie, R. E.; VanDecar, J. C. (American Geophysical Union, 2013)
      We located continuous seismic tremor with coherent amplitude wave trains in the Chile ridge subduction region (~46.5 S) in two clusters north and south of the Chonos Archipelago, between the Chile trench and the North ...

      An experimental study is made of the time decay of activity of the CO-NO reaction on a Pd/Al2O3 looking at the effect on reaction order and apparent activation energy. The optimum kinetics parameters fitting the steady ...
    • Time Dilation In The Light Curve Of The Distant Type Ia Supernova Sn 1995k 
      Leibundgut, B.; Schommer, R.; Phillips, M. M.; Riess, A.; Schmidt, B.; Spyromilio, J.; Walsh, J.; Suntzeff, Nicholas B.; Hamuy Wackenhut, Mario; Maza Sancho, José; Kirshner, R. P.; Challis, P.; Garnavich, P.; Smith, R. C.; Dressler, A.; Ciardullo, R. (The American Astronomical Society, 1996-07-20)
      The light curve of a distant Type Ia supernova acts like a clock that can be used to test the expansion of the universe. SN 1995K, at a spectroscopic redshift of z = 0.479, provides one of the first meaningful data sets ...
