In this contribution we present the analysis of the ionization structure of a sample of six low-z Ultraluminous Infrared Galaxies using Integral Field...

Line intensity ratio has been used in astronomy to calculate plasma density and temperature. This procedure is applied to monitor thin film growth in plasma...

The dwarf irregular galaxy IC10 in Cassiopeia, is the youngest available starburst galaxy and home to many X-ray sources. Using the Gemini multi-object...

We performed optical spectroscopy of the candidates inside the gravitational wave errorboxes (S190408an, S190425z, S190426c, S190510g, S190728q, S190814bv). The...

In response to the detection of the X-ray source Swift J0732.5-1331 (ATEL #697, #735, #757, #760), we observed its optical counterpart with the Mt. Hopkins 1.5m...

Spectra of the optical counterpart to the gamma ray source SWIFT J1753.5-0127 (ATEL #546,#547,#549,#550) were acquired on 2005 July 3th 03:52-09:48 UT with the...

Optical spectra (range 600-690 nm; resolution 6000) were obtained during the current outburst of this black hole binary on July 4.65-4.75 UT with the Siding...

A single 30 min high-resolution spectrum of the optical counterpart to the black hole candidate XTE J1817-330 (ATEL #714, #733) was acquired with the MIKE...
