Parity in Planck full-mission CMB temperature maps

Srikanta Panda, Pavan K. Aluri, Pramoda Kumar Samal +1

In the standard model of cosmology, Cosmic Microwave Background (CMB) sky is expected to show no symmetry preferences. Following our previous studies, we explore the presence of an…

Testing isotropy of cosmos with WMAP and PLANCK data

Pranati K. Rath, Pramoda Kumar Samal

In recent years, there have been a large number of studies which support violation of statistical isotropy. Meanwhile, there are some studies which also found inconsistency. We use…

Testing statistical Isotropy in Cosmic Microwave Background Polarization maps

Pranati K. Rath, Pramoda Kr. Samal, Srikanta Panda +2

We apply our symmetry based Power tensor technique to test conformity of PLANCK Polarization maps with statistical isotropy. On a wide range of angular scales (l=40-150), our preli…

SOAR Imaging of sub-Damped Lyman-Alpha Systems at z<1

Joseph D. Meiring, James T. Lauroesch, Lutz Haberzettl +4

We present deep ground based imaging of the environments of five QSOs that contain sub-Damped Lyman-alpha systems at z<1 with the SOAR telescope and SOI camera. We detect a clear s…

Effect of Foregrounds on the CMBR Multipole Alignment

Pavan K. Aluri, Pramoda K. Samal, Pankaj Jain +1

We analyze the effect of foregrounds on the observed alignment of CMBR quadrupole and octopole. The alignment between these multipoles is studied by using a symmetry based approach…

A MIKE + UVES survey of Sub-Damped Lyman-Alpha Systems at z<1.5

Joseph D. Meiring, James T. Lauroesch, Varsha P. Kulkarni +3

We have combined the results from our recent observations of Damped and sub-Damped Lyman-alpha systems with the MIKE and UVES spectrographs on the Magellan Clay and VLT Kueyen tele…
