Intra-night optical variability monitoring of -ray emitting blazars
K. Subbu Ulaganatha Pandian, A. Natarajan, C. S. Stalin +3
We present the results obtained from our campaign to characterize the intra-night-optical variability properties of blazars detected by the {\it Fermi} Large Area Telescope. This i…
Green Bank Telescope Constraints on Dark Matter Annihilation in Segue I
Aravind Natarajan, James E. Aguirre, Kristine Spekkens +1
We use a non-detection in GHz Green Bank Telescope observations of the ultra-faint dwarf spheroidal galaxy Segue I, which could be immersed in a non-negligible halo magne…
Probing the Small Scale Matter Power Spectrum through Dark Matter Annihilation in the Early Universe
Aravind Natarajan, Nick Zhu, Naoki Yoshida
Recent observations of the cosmic microwave background (CMB) anisotropies and the distribution of galaxies, galaxy clusters, and the Lyman Alpha forest have constrained the shape o…
Indirect Probes of Dark Matter and Globular Cluster Properties From Dark Matter Annihilation within the Coolest White Dwarfs
Travis J. Hurst, Andrew R. Zentner, Aravind Natarajan +1
White Dwarfs (WD) capture Dark Matter (DM) as they orbit within their host halos. These captured particles may subsequently annihilate, heating the stellar core and preventing the…
Measuring the 21 cm Global Brightness Temperature Spectrum During the Dark Ages with the SCI-HI Experiment
Jeffrey B. Peterson, Tabitha C. Voytek, Aravind Natarajan +2
We present an update on the SCI-HI experiment, which is designed to measure the all-sky (global) 21 cm brightness temperature during the end of the Dark Ages. Results from prelimin…
Systematic errors in the measurement of neutrino masses due to baryonic feedback processes: Prospects for stage IV lensing surveys
Aravind Natarajan, Andrew R. Zentner, Nicholas Battaglia +1
We examine the importance of baryonic feedback effects on the matter power spectrum on small scales, and the implications for the precise measurement of neutrino masses through gra…
