The LTP (LISA Testflight Package), to be flown aboard the ESA / NASA LISA Pathfinder mission, aims to demonstrate drag-free control for LISA test masses with acceleration noise below 30 fm /s/ √ Hz from 1-30 mHz. This paper describes the LTP measurement of random, position independent forces acting on the test masses. In addition to putting an overall upper limit for all source of random force ...

The multiple Doppler readouts available on the Laser Interferometer Space Antenna (LISA) permit simultaneous formation of several interferometric observables. All these observables are independent of laser frequency fluctuations and have different couplings to gravitational waves and to the various LISA instrumental noises. Within the functional space of interferometric combinations LISA will b...

The development of application specific instruction set processors comprises several design phases: architecture exploration, software tools design, system verification and design implementation. The LISA processor design platform (LPDP) based on machine descriptions in the LISA language provides one common environment for these design phases. Required software tools for architecture exploratio...

One of the most exciting potential sources of gravitational waves for the Laser Interferometer Space Antenna (LISA) are the inspirals of approximately solar mass compact objects into massive black holes in the centres of galaxies — extreme mass ratio inspirals (EMRIs). LISA should observe between a few tens and a few hundred EMRIs over the mission lifetime, mostly at low redshifts (z . 1). Each...

The magnitudes of the external gravitational perturbations associated with the normal modes of the Sun are evaluated to determine whether these solar oscillations could be observed with the proposed Laser Interferometer Space Antenna (LISA), a network of satellites designed to detect gravitational radiation. The modes of relevance to LISA—the l = 2, low-order p, f and g-modes—have not been conc...

This paper describes the LISA system which is a generic interactive environment for programming language development. From the formal language specifications of a particular programming language LISA produces a language specific environment that includes a languageknowledgable editor, a compiler/interpreter and other graphic tools. The paper focuses on design decisions, implementation issues an...

{ This paper presents the machine description language LISA for the generation of bit-and cycle accurate models of DSP processors. Based on a behavioral operation description, the architectural details and pipeline operations of modern DSP processors can be covered. Beyond the behavioral model, LISA descriptions include other architecture-related information like the instruction set. The inform...
