Stellar and Gaseous Disk Structures in Cosmological Galaxy Equilibrium Models

Ben Rathaus, Amiel Sternberg

We present "radially-resolved-equilibrium-models" for the growth of stellar and gaseous disks in cosmologically accreting massive halos. Our focus is on objects that evolve to reds…

The CMB Derivatives of Planck's Beam Asymmetry

Ben Rathaus, Ely D. Kovetz

We investigate the anisotropy in cosmic microwave background Planck maps due to the coupling between its beam asymmetry and uneven scanning strategy. Introducing a pixel space esti…

Studying the Peculiar Velocity Bulk Flow in a Sparse Survey of Type-Ia SNe

Ben Rathaus, Ely D. Kovetz, Nissan Itzhaki

Studies of the peculiar velocity bulk flow based on different tools and datasets have been consistent so far in their estimation of the direction of the flow, which also happens to…

Orbifold Line Topology and the Cosmic Microwave Background

Ben Rathaus, Assaf Ben-David, Nissan Itzhaki

We extend our study of a universe with a non-classical stringy topology, and consider an orbifold line topology, . This topology has a fi…

Searching for Stringy Topologies in the Cosmic Microwave Background

Assaf Ben-David, Ben Rathaus, Nissan Itzhaki

We consider a universe with a non-classical stringy topology that has fixed points. We concentrate on the simplest example, an orbifold point, and study its observable imprints on…

CMB Lensing and Giant Rings

Ben Rathaus, Nissan Itzhaki

We study the CMB lensing signature of a pre-inationary particle (PIP), assuming it is responsible for the giant rings anomaly that was found recently in the WMAP data. Simulating P…

How Sensitive is the CMB to a Single Lens?

Ben Rathaus, Anastasia Fialkov, Nissan Itzhaki

We study the imprints of a single lens, that breaks statistical isotropy, on the CMB and calculate the signal to noise ratio (S/N) for its detection. We emphasize the role of non-G…
