We present narrowband images of eta Carinae in the light of [O III] 5007 obtained with HST/WFPC2, as well as a ground-based image in the same emission line with a larger field of view. These images show a thin veil of [O III] emission around eta Ca...
We present images and spectra of a ~10 kpc-sized emission-line nebulosity discovered in the prototypical merger remnant NGC 7252 and dubbed the `[O III] nebula' because of its dominant [O III]_5007 line. This nebula seems to yield the first sign of e...
Indian Institute of Technology Kharagpur (IIT Kharagpur or IIT KGP) is a public institute of technology, research university, and autonomous institute established
We provide a status report on our current understanding of the mass scales for Pop III.1 and Pop III.2 stars. Since the last review (Norman 2008), substantial progress has been made both numerically and analytically on the late stages of protostellar...
Boris III (Bulgarian: Борѝс III; Boris Treti; 30 January [O.S. 18 January] 1894 – 28 August 1943) was the Tsar of the Kingdom of Bulgaria from 1918 until
We calculate nucleosynthesis in core-collapse explosions of massive Pop III stars, and compare the results with abundances of metal-poor halo stars to constrain the parameters of Pop III supernovae. We focus on iron-peak elements and, in particular...
Stepfather III (also known as Stepfather III: Father's Day) is a 1992 American horror film directed and written by Guy Magar. It stars Robert Wightman
A review of Peter Byrne's biography of Hugh Everett III, "The Many Worlds of Hugh Everett III: Multiple Universes, Mutual Assured Destruction, and the Meltdown of a Nuclear Family", (Oxford University Press, 2010)....
Anthony Aguirre and Max Tegmark have famously speculated that the Level I Multiverse is the same as the Level III Multiverse. By this, they mean that the parallel universes of the Level III Multiverse can be regarded as similar or identical copies of...
In order to complete Stark broadening data for Ne II, and O III lines, needed for analysis of stellar atmospheres, we determined, within the semiclassical perturbation method, the missing Stark broadening parameters for the broadening by collisions w...
Right now we've got a bunch of IIS 10 site with the SMTP email setting configured to pass emails to an ancient IIS 6 SMTP Relay server, which in turn distributes our automated reporting emails. To re...
We review recent 3D cosmological hydrodynamic simulations of primordial star formation from cosmological initial conditions (Pop III.1) and from initial conditions that have been altered by radiative feedback from stellar sources (Pop III.2). We co...
With the launch of JWST and other scheduled missions aimed at probing the distant Universe, we are entering a new promising era for high-$z$ astronomy. One of our main goals is the detection of the first population of stars (Population III or Pop III...
