Monitoring luminous yellow massive stars in M33: new yellow hypergiant candidates
M. Kourniotis, A. Z. Bonanos, W. Yuan +3
The evolution of massive stars surviving the red supergiant (RSG) stage remains unexplored due to the rarity of such objects. The yellow hypergiants (YHGs) appear to be the warm co…
Period estimation for sparsely-sampled quasi-periodic light curves applied to Miras
Shiyuan He, Wenlong Yuan, Jianhua Z. Huang +2
We develop a non-linear semi-parametric Gaussian process model to estimate periods of Miras with sparsely-sampled light curves. The model uses a sinusoidal basis for the periodic v…
Optical Identification of Cepheids in 19 Host Galaxies of Type Ia Supernovae and NGC 4258 with the Hubble Space Telescope
Samantha L. Hoffmann, Lucas M. Macri, Adam G. Riess +10
We present results of an optical search for Cepheid variable stars using the Hubble Space Telescope (HST) in 19 hosts of Type Ia supernovae (SNe Ia) and the maser-host galaxy NGC 4…
GW150914: First search for the electromagnetic counterpart of a gravitational-wave event by the TOROS collaboration
Mario C. Díaz, Martín Beroiz, Tania Peñuela +31
We present the results of the optical follow-up conducted by the TOROS collaboration of the first gravitational-wave event GW150914. We conducted unfiltered CCD observations (0.35-…
A 2.4% Determination of the Local Value of the Hubble Constant
Adam G. Riess, Lucas M. Macri, Samantha L. Hoffmann +12
We use the Wide Field Camera 3 (WFC3) on the Hubble Space Telescope (HST) to reduce the uncertainty in the local value of the Hubble constant (H_0) from 3.3% to 2.4%. Improvements…
