Probing the accelerating Universe with radio weak lensing in the JVLA Sky Survey
M. L. Brown, F. B. Abdalla, A. Amara +48
We outline the prospects for performing pioneering radio weak gravitational lensing analyses using observations from a potential forthcoming JVLA Sky Survey program. A large-scale…
The Atlas3D project -- XXVII. Cold Gas and the Colours and Ages of Early-type Galaxies
L. M. Young, N. Scott, P. Serra +22
We present a study of the cold gas contents of the Atlas3D early-type galaxies, in the context of their optical colours, near-UV colours, and Hβ absorption line strengths. Early-ty…
Improved Hubble Space Telescope Proper Motions for Tycho-G and Other Stars in the Remnant of Tycho's Supernova 1572
L. R. Bedin, P. Ruiz-Lapuente, J. I. Gonzalez Hernandez +4
With archival and new Hubble Space Telescope observations we have refined the space-velocity measurements of the stars in the central region of the remnant of Tycho's supernova (SN…
Signatures of anisotropic sources in the trispectrum of the cosmic microwave background
Maresuke Shiraishi, Eiichiro Komatsu, Marco Peloso
Soft limits of -point correlation functions, in which one wavenumber is much smaller than the others, play a special role in constraining the physics of inflation. Anisotropic s…
Measurement of acoustic glitches in solar-type stars from oscillation frequencies observed by Kepler
A. Mazumdar, M. J. P. F. G. Monteiro, J. Ballot +15
For the very best and brightest asteroseismic solar-type targets observed by Kepler, the frequency precision is sufficient to determine the acoustic depths of the surface convectiv…
A new procedure for defining a homogenous line-list for solar-type stars
S. G. Sousa, N. C. Santos, V. Adibekyan +9
Context. The homogenization of the stellar parameters is an important goal for large observational spectroscopic surveys, but it is very difficult to achieve it because of the dive…
Production of Nickel-56 in black hole-neutron star merger accretion disk outflows
R. Surman, O. L. Caballero, G. C. McLaughlin +2
The likely outcome of a compact object merger event is a central black hole surrounded by a rapidly accreting torus of debris. This disk of debris is a rich source of element synth…
The Mass-Concentration-Redshift Relation of Cold Dark Matter Halos
Aaron D. Ludlow, Julio F. Navarro, Raul E. Angulo +4
We use the Millennium Simulation series to investigate the mass and redshift dependence of the concentration of equilibrium cold dark matter (CDM) halos. We extend earlier work on…
NGC1266 as a Local Candidate for Rapid Cessation of Star Formation
Katherine Alatalo, Kristina Nyland, Genevieve Graves +27
We present new Spectrographic Areal Unit for Research on Optical Nebulae (SAURON) integral-field spectroscopy and Swift Ultraviolet Optical Telescope (UVOT) observations of molecul…
A thin diffuse component of the Galactic Ridge X-ray emission and heating of the interstellar medium contributed by the radiation of Galactic X-ray binaries
Margherita Molaro, Rishi Khatri, Rashid Sunyaev
We predict a thin (scale height 80 pc) diffuse component of the Galactic Ridge X-ray emission (GRXE) arising from the scattering of the radiation of bright X-ray binaries (X…
Large-Scale Structure and Gravitational Waves III: Tidal Effects
Fabian Schmidt, Enrico Pajer, Matias Zaldarriaga
The leading locally observable effect of a long-wavelength metric perturbation corresponds to a tidal field. We derive the tidal field induced by scalar, vector, and tensor perturb…
Planck intermediate results. XVII. Emission of dust in the diffuse interstellar medium from the far-infrared to microwave frequencies
Planck Collaboration, A. Abergel, P. A. R. Ade +196
The dust-HI correlation is used to characterize the emission properties of dust in the diffuse interstellar medium. We cross-correlate sky maps from Planck, WMAP, and DIRBE, at 17…
Mapping dark matter in the gamma-ray sky with galaxy catalogs
Shin'ichiro Ando, Aurélien Benoit-Lévy, Eiichiro Komatsu
Cross-correlating gamma-ray maps with locations of galaxies in the low-redshift Universe vastly increases sensitivity to signatures of annihilation of dark matter particles. Low-re…
Impact of thermal diffusion and other abundance anomalies on cosmological uses of galaxy clusters
P. Medvedev, M. Gilfanov, S. Sazonov +1
Depending on the topology of the magnetic field and characteristics of turbulent motions, diffusion can significantly affect the distribution of elements, in particular helium, in…
The Mutual Interaction Between Population III Stars and Self-Annihilating Dark Matter
Athena Stacy, Andreas H. Pawlik, Volker Bromm +1
We use cosmological simulations of high-redshift minihalos to investigate the effect of dark matter annihilation (DMA) on the collapse of primordial gas. We numerically investigate…
Computation of the Halo Mass Function Using Physical Collapse Parameters: Application to Non-Standard Cosmologies
I. Achitouv, C. Wagner, J. Weller +1
In this article we compare the halo mass function predicted by the excursion set theory with a drifting diffusive barrier against the results of N-body simulations for several cosm…
Log-transforming the matter power spectrum
Maksim Greiner, Torsten A. Enßlin
We investigate whether non-linear effects on the large-scale power spectrum of dark matter, namely the increase in small-scale power and the smearing of baryon acoustic oscillation…
Improving self-calibration
Torsten A. Enßlin, Henrik Junklewitz, Lars Winderling +2
Response calibration is the process of inferring how much the measured data depend on the signal one is interested in. It is essential for any quantitative signal estimation on the…
