Photometric Redshifts of Galaxies in COSMOS
B. Mobasher, P. Capak, N. Z. Scoville +26
We measure photometric redshifts and spectral types for galaxies in the COSMOS survey. We use template fitting technique combined with luminosity function priors and with the optio…
Tentative detection of the gravitational magnification of type Ia supernovae
Jakob Jonsson, Tomas Dahlen, Ariel Goobar +2
The flux from distant type Ia supernovae (SN) is likely to be amplified or de-amplified by gravitational lensing due to matter distributions along the line-of-sight. A gravitationa…
Application of an XMM-Newton EPIC Monte Carlo Technique to Analysis and Interpretation of Data for the Abell 1689, RX J0658-55 and Centaurus clusters of galaxies
K. E. Andersson, J. R. Peterson, G. M. Madejski
We propose a new Monte Carlo method to study extended X-ray sources with the European Photon Imaging Camera (EPIC) aboard {\sl XMM-Newton}. The smoothed particle inference (SPI) te…
Dark Matter on the Smallest Scales
E. R. Siegel, G. D'Amico, E. Di Napoli +5
This work investigates the dark matters structures that form on the smallest cosmological scales. We find that the types and abundances of structures which form at approximately Ea…
The Peculiar Type Ia Supernova 2005hk
V. Stanishev, S. Taubenberger, G. Blanc +15
We present a preliminary analysis of an extensive set of optical observations of the Type Ia SN 2005hk. We show that the evolution of SN 2005hk closely follows that of the peculiar…
Tuning Gravitationally Lensed Standard Sirens
Jakob Jonsson, Ariel Goobar, Edvard Mortsell
Gravitational waves emitted by chirping supermassive black hole binaries could in principle be used to obtain very accurate distance determinations. Provided they have an electroma…
Five years of searches for point sources of astrophysical neutrinos with the AMANDA-II neutrino telescope
A. Achterberg
We report the results of a five-year survey of the northern sky to search for point sources of high energy neutrinos. The search was performed on the data collected with the AMANDA…
Type Ia SNe along redshift: the R(Si II) ratio and the expansion velocities in intermediate z supernovae
G. Altavilla, P. Ruiz-Lapuente, A. Balastegui +17
We study intermediate--z SNe Ia using the empirical physical diagrams which enable to learn about those SNe explosions. This information can be very useful to reduce systematic unc…
Reconstructing the Thomson Optical Depth due to Patchy Reionization with 21-cm Fluctuation Maps
Gilbert Holder, Ilian T. Iliev, Garrelt Mellema
Large fluctuations in the electron column density can occur during the reionization process. We investigate the possibility of deriving the electron density fluctuations through de…
Shining light through the Sun
Malcolm Fairbairn, Timur Rashba, Sergey Troitsky
It is shown that the Sun can become partially transparent to high energy photons in the presence of a pseudo-scalar. In particular, if the axion interpretation of the PVLAS result…
Halting Type I planet migration in non-isothermal disks
S. -J. Paardekooper, G. Mellema
Aims: We investigate the effect of including a proper energy balance on the interaction of a low-mass planet with a protoplanetary disk. Methods: We use a three-dimensional version…
Spitzer measurements of atomic and molecular abundances in the Type IIP SN 2005af
Rubina Kotak, Peter Meikle, Monica Pozzo +12
We present results based on Spitzer Space Telescope mid-infrared (3.6-30 micron) observations of the nearby IIP supernova 2005af. We report the first ever detection of the SiO mole…
The Kinetic Sunyaev-Zel'dovich Effect from Radiative Transfer Simulations of Patchy Reionization
Ilian T. Iliev, Ue-Li Pen, J. Richard Bond +2
We present the first calculation of the kinetic Sunyaev-Zel'dovich (kSZ) effect due to the inhomogeneous reionization of the universe based on detailed large-scale radiative transf…
On the selection of AGN neutrino source candidates for a source stacking analysis with neutrino telescopes
A. Achterberg et al.
The sensitivity of a search for sources of TeV neutrinos can be improved by grouping potential sources together into generic classes in a procedure that is known as source stacking…
The Type Ia supernova 2004S, a clone of SN 2001el, and the optimal photometric bands for extinction estimation
Kevin Krisciunas, Peter M. Garnavich, Vallery Stanishev +9
We present optical (UBVRI) and near-infrared (YJHK) photometry of the normal Type Ia supernova 2004S. We also present eight optical spectra and one near-IR spectrum of SN 2004S. Th…
Evolution of the Luminosity Function, Star Formation Rate, Morphology and Size of Star-forming Galaxies Selected at Rest-frame 1500A and 2800A
Tomas Dahlen, Bahram Mobasher, Mark Dickinson +4
Using the multiwavelength photometric and spectroscopic data covering the CDF-S obtained within the GOODS, we investigate the rest-frame UV properties of galaxies to z~2.2, includi…
SN 2004aw: Confirming Diversity of Type Ic Supernovae
