TL;DR
The LEM All-Sky Survey (LASS) will provide the first high spectral resolution, microcalorimeter-based survey of the entire X-ray sky, enabling new insights into the hot phases of the Milky Way and beyond.
Contribution
This paper introduces the LEM All-Sky Survey, a novel high-resolution X-ray survey with microcalorimeter technology covering the whole sky, surpassing previous surveys in spectral and spatial capabilities.
Findings
LASS will deliver high spectral resolution data for the entire sky.
It will enable detailed studies of the Milky Way's hot gas and point sources.
The survey will facilitate new discoveries in X-ray astrophysics.
Abstract
The Line Emission Mapper (LEM) is an X-ray Probe with with spectral resolution ~2 eV FWHM from 0.2 to 2.5 keV and effective area >2,500 cm at 1 keV, covering a 33 arcmin diameter Field of View with 15 arcsec angular resolution, capable of performing efficient scanning observations of very large sky areas and enabling the first high spectral resolution survey of the full sky. The LEM-All-Sky Survey (LASS) is expected to follow the success of previous all sky surveys such as ROSAT and eROSITA, adding a third dimension provided by the high resolution microcalorimeter spectrometer, with each 15 arcsec pixel of the survey including a full 1-2 eV resolution energy spectrum that can be integrated over any area of the sky to provide statistical accuracy. Like its predecessors, LASS will provide both a long-lasting legacy and open the door to the unknown, enabling new discoveries and…
