New Constraints on Macroscopic Compact Objects as a Dark Matter Candidate from Gravitational Lensing of Type Ia Supernovae
R. Benton Metcalf, Joseph Silk
We use the distribution, and particularly the skewness, of high redshift type Ia supernovae brightnesses relative to the low redshift sample to constrain the density of macroscopic…
Active galactic nuclei and massive galaxy cores
Sebastien Peirani, Scott Kay, Joe Silk
(Context) Central active galactic nuclei (AGN) are supposed to play a key role in the evolution of their host galaxies. In particular, the dynamical and physical properties of the…
Local Voids as the Origin of Large-angle Cosmic Microwave Background Anomalies: The Effect of a Cosmological Constant
Kaiki Taro Inoue, Joseph Silk
We explore the large angular scale temperature anisotropies in the cosmic microwave background (CMB) due to homogeneous local dust-filled voids in a flat Friedmann-Robertson-Walker…
Disk Galaxy Evolution Along the Hubble Sequence
Marios Kampakoglou, Joseph Silk
Galaxy disks are characterised by star formation histories that vary systematically along the Hubble sequence. We study global star formation, incorporating supernova feedback, gas…
Observables sensitive to absolute neutrino masses: A reappraisal after WMAP-3y and first MINOS results
G. L. Fogli, E. Lisi, A. Marrone +5
In the light of recent neutrino oscillation and non-oscillation data, we revisit the phenomenological constraints applicable to three observables sensitive to absolute neutrino mas…
Luminosity Function of Faint Globular Clusters in M87
Christopher Z. Waters, Stephen E. Zepf, Tod R. Lauer +2
We present the luminosity function to very faint magnitudes for the globular clusters in M87, based on a 30 orbit \textit{Hubble Space Telescope (HST)} WFPC2 imaging program. The v…
