When discovered, SN 2017egm was the closest (redshift z = 0.03) hydrogen-poor superluminous supernova (SLSN-I) and a rare case that exploded in a massive and metal-rich galaxy. Thus, it has since been extensively observed and studied. We report spect

V2944 Ophiuchi was a Fe ii type novae that reached moderate excitation and displayed large variations among the profiles of its emission lines. The profiles become increasingly double-peaked as the ionization level of the parent ion increases. At the

Spectroscopy from 0.46–2.5 μm is presented for the 2022 outburst of the recurrent nova U Scorpii from 2.54, 3.60, and 8.59 days after maximum light. During this period the spectra evolved from comparatively low excitation to the verge of displayin

Nova V5856 Sagittarii is unique for having remained more than nine magnitudes above its pre-outburst brightness for more than six years. Extensive visible and IR spectra from the time of outburst to the present epoch reveal separate emitting regions

Infrared spectroscopy of the recurrent nova U Scorpii from 14.2 days after its 2010 outburst reveals two very strong infrared coronal lines: [Si x] at 1.4305 μm and [Al ix] at 2.0400 μm. Taken together with the detection of coronal lines in the 202

0.47–2.45 μm spectroscopy is reported for the compact planetary nebula Minkowski 4-18 (PK146+07), filling some spectral gaps and presenting uniform and simultaneous observation of this entire spectral range. While the strongest features are the H

Visible and infrared spectra, from two, widely separated epochs, are presented for the nova V606 Vulpeculae. The first, acquired 7 days after the nova reached maximum light, displayed emission from carbon monoxide plus a wealth of low excitation atom

V5588 Sagittarii (Nova Sagittarii 2011 No. 2) was one of the rare novae that undergo outbursts after the initial explosion, and was extreme in that it did so six times. We present 0.8–5.1 μm spectroscopy acquired during the second of these so-call
