Non-perturbative probability distribution function for cosmological counts in cells
Mikhail M. Ivanov, Alexander A. Kaurov, Sergey Sibiryakov
We present a non-perturbative calculation of the 1-point probability distribution function (PDF) for the spherically-averaged matter density field. The PDF is represented as a path…
Implication of the Shape of the EDGES Signal for the 21 cm Power Spectrum
Alexander A. Kaurov, Tejaswi Venumadhav, Liang Dai +1
We revisit the 21 cm power spectrum from the epoch of cosmic dawn in light of the recent EDGES detection of the 21 cm global signal at frequencies corresponding to . The s…
Heating of the intergalactic medium by the cosmic microwave background during cosmic dawn
Tejaswi Venumadhav, Liang Dai, Alexander Kaurov +1
The intergalactic medium is expected to be at its coldest point before the formation of the first stars in the universe. Motivated by recent results from the EDGES experiment, we r…
Probing Dark Matter Subhalos in Galaxy Clusters Using Highly Magnified Stars
Liang Dai, Tejaswi Venumadhav, Alexander A. Kaurov +1
Luminous stars in background galaxies straddling the lensing caustic of a foreground galaxy cluster can be individually detected due to extreme magnification factors of …
